+What:           /sys/dev
+Date:           April 2008
+KernelVersion:  2.6.26
+Contact:        Dan Williams <dan.j.williams@intel.com>
+Description:    The /sys/dev tree provides a method to look up the sysfs
+                path for a device using the information returned from
+                stat(2).  There are two directories, 'block' and 'char',
+                beneath /sys/dev containing symbolic links with names of
+                the form "<major>:<minor>".  These links point to the
+                corresponding sysfs path for the given device.
+
+                Example:
+                $ readlink /sys/dev/block/8:32
+                ../../block/sdc
+
+                Entries in /sys/dev/char and /sys/dev/block will be
+                dynamically created and destroyed as devices enter and
+                leave the system.

+Paravirt_ops on IA64
+====================
+                          21 May 2008, Isaku Yamahata <yamahata@valinux.co.jp>
+
+
+Introduction
+------------
+The aim of this documentation is to help with maintainability and/or to
+encourage people to use paravirt_ops/IA64.
+
+paravirt_ops (pv_ops in short) is a way for virtualization support of
+Linux kernel on x86. Several ways for virtualization support were
+proposed, paravirt_ops is the winner.
+On the other hand, now there are also several IA64 virtualization
+technologies like kvm/IA64, xen/IA64 and many other academic IA64
+hypervisors so that it is good to add generic virtualization
+infrastructure on Linux/IA64.
+
+
+What is paravirt_ops?
+---------------------
+It has been developed on x86 as virtualization support via API, not ABI.
+It allows each hypervisor to override operations which are important for
+hypervisors at API level. And it allows a single kernel binary to run on
+all supported execution environments including native machine.
+Essentially paravirt_ops is a set of function pointers which represent
+operations corresponding to low level sensitive instructions and high
+level functionalities in various area. But one significant difference
+from usual function pointer table is that it allows optimization with
+binary patch. It is because some of these operations are very
+performance sensitive and indirect call overhead is not negligible.
+With binary patch, indirect C function call can be transformed into
+direct C function call or in-place execution to eliminate the overhead.
+
+Thus, operations of paravirt_ops are classified into three categories.
+- simple indirect call
+  These operations correspond to high level functionality so that the
+  overhead of indirect call isn't very important.
+
+- indirect call which allows optimization with binary patch
+  Usually these operations correspond to low level instructions. They
+  are called frequently and performance critical. So the overhead is
+  very important.
+
+- a set of macros for hand written assembly code
+  Hand written assembly codes (.S files) also need paravirtualization
+  because they include sensitive instructions or some of code paths in
+  them are very performance critical.
+
+
+The relation to the IA64 machine vector
+---------------------------------------
+Linux/IA64 has the IA64 machine vector functionality which allows the
+kernel to switch implementations (e.g. initialization, ipi, dma api...)
+depending on executing platform.
+We can replace some implementations very easily defining a new machine
+vector. Thus another approach for virtualization support would be
+enhancing the machine vector functionality.
+But paravirt_ops approach was taken because
+- virtualization support needs wider support than machine vector does.
+  e.g. low level instruction paravirtualization. It must be
+       initialized very early before platform detection.
+
+- virtualization support needs more functionality like binary patch.
+  Probably the calling overhead might not be very large compared to the
+  emulation overhead of virtualization. However in the native case, the
+  overhead should be eliminated completely.
+  A single kernel binary should run on each environment including native,
+  and the overhead of paravirt_ops on native environment should be as
+  small as possible.
+
+- for full virtualization technology, e.g. KVM/IA64 or
+  Xen/IA64 HVM domain, the result would be
+  (the emulated platform machine vector. probably dig) + (pv_ops).
+  This means that the virtualization support layer should be under
+  the machine vector layer.
+
+Possibly it might be better to move some function pointers from
+paravirt_ops to machine vector. In fact, Xen domU case utilizes both
+pv_ops and machine vector.
+
+
+IA64 paravirt_ops
+-----------------
+In this section, the concrete paravirt_ops will be discussed.
+Because of the architecture difference between ia64 and x86, the
+resulting set of functions is very different from x86 pv_ops.
+
+- C function pointer tables
+They are not very performance critical so that simple C indirect
+function call is acceptable. The following structures are defined at
+this moment. For details see linux/include/asm-ia64/paravirt.h
+  - struct pv_info
+    This structure describes the execution environment.
+  - struct pv_init_ops
+    This structure describes the various initialization hooks.
+  - struct pv_iosapic_ops
+    This structure describes hooks to iosapic operations.
+  - struct pv_irq_ops
+    This structure describes hooks to irq related operations
+  - struct pv_time_op
+    This structure describes hooks to steal time accounting.
+
+- a set of indirect calls which need optimization
+Currently this class of functions correspond to a subset of IA64
+intrinsics. At this moment the optimization with binary patch isn't
+implemented yet.
+struct pv_cpu_op is defined. For details see
+linux/include/asm-ia64/paravirt_privop.h
+Mostly they correspond to ia64 intrinsics 1-to-1.
+Caveat: Now they are defined as C indirect function pointers, but in
+order to support binary patch optimization, they will be changed
+using GCC extended inline assembly code.
+
+- a set of macros for hand written assembly code (.S files)
+For maintenance purpose, the taken approach for .S files is single
+source code and compile multiple times with different macros definitions.
+Each pv_ops instance must define those macros to compile.
+The important thing here is that sensitive, but non-privileged
+instructions must be paravirtualized and that some privileged
+instructions also need paravirtualization for reasonable performance.
+Developers who modify .S files must be aware of that. At this moment
+an easy checker is implemented to detect paravirtualization breakage.
+But it doesn't cover all the cases.
+
+Sometimes this set of macros is called pv_cpu_asm_op. But there is no
+corresponding structure in the source code.
+Those macros mostly 1:1 correspond to a subset of privileged
+instructions. See linux/include/asm-ia64/native/inst.h.
+And some functions written in assembly also need to be overrided so
+that each pv_ops instance have to define some macros. Again see
+linux/include/asm-ia64/native/inst.h.
+
+
+Those structures must be initialized very early before start_kernel.
+Probably initialized in head.S using multi entry point or some other trick.
+For native case implementation see linux/arch/ia64/kernel/paravirt.c.

+X - Specifying Device Power Management Information (sleep property)
+===================================================================
+
+Devices on SOCs often have mechanisms for placing devices into low-power
+states that are decoupled from the devices' own register blocks.  Sometimes,
+this information is more complicated than a cell-index property can
+reasonably describe.  Thus, each device controlled in such a manner
+may contain a "sleep" property which describes these connections.
+
+The sleep property consists of one or more sleep resources, each of
+which consists of a phandle to a sleep controller, followed by a
+controller-specific sleep specifier of zero or more cells.
+
+The semantics of what type of low power modes are possible are defined
+by the sleep controller.  Some examples of the types of low power modes
+that may be supported are:
+
+ - Dynamic: The device may be disabled or enabled at any time.
+ - System Suspend: The device may request to be disabled or remain
+   awake during system suspend, but will not be disabled until then.
+ - Permanent: The device is disabled permanently (until the next hard
+   reset).
+
+Some devices may share a clock domain with each other, such that they should
+only be suspended when none of the devices are in use.  Where reasonable,
+such nodes should be placed on a virtual bus, where the bus has the sleep
+property.  If the clock domain is shared among devices that cannot be
+reasonably grouped in this manner, then create a virtual sleep controller
+(similar to an interrupt nexus, except that defining a standardized
+sleep-map should wait until its necessity is demonstrated).

+  apply to "fsl,mpc8641d-pmc".
+
+  Compatibility does not include bit assigments in SCCR/PMCDR/DEVDISR; these
+  bit assigments are indicated via the sleep specifier in each device's
+  sleep property.
+
+- reg: For devices compatible with "fsl,mpc8349-pmc", the first resource
+  is the PMC block, and the second resource is the Clock Configuration
+  block.
+
+  For devices compatible with "fsl,mpc8548-pmc", the first resource
+  is a 32-byte block beginning with DEVDISR.
+
+- interrupts: For "fsl,mpc8349-pmc"-compatible devices, the first
+  resource is the PMC block interrupt.
+
+- fsl,mpc8313-wakeup-timer: For "fsl,mpc8313-pmc"-compatible devices,

+  a wakeup source from deep sleep.
+
+Sleep specifiers:
+
+  fsl,mpc8349-pmc: Sleep specifiers consist of one cell.  For each bit
+  that is set in the cell, the corresponding bit in SCCR will be saved
+  and cleared on suspend, and restored on resume.  This sleep controller
+  supports disabling and resuming devices at any time.
+
+  fsl,mpc8536-pmc: Sleep specifiers consist of three cells, the third of
+  which will be ORed into PMCDR upon suspend, and cleared from PMCDR
+  upon resume.  The first two cells are as described for fsl,mpc8578-pmc.
+  This sleep controller only supports disabling devices during system
+  sleep, or permanently.
+
+  fsl,mpc8548-pmc: Sleep specifiers consist of one or two cells, the
+  first of which will be ORed into DEVDISR (and the second into
+  DEVDISR2, if present -- this cell should be zero or absent if the
+  hardware does not have DEVDISR2) upon a request for permanent device
+  disabling.  This sleep controller does not support configuring devices

+  match), or dynamically.

-This document and the new uhci sources can be found on
-                http://hotswap.in.tum.de/usb
-
-1. General issues
-
-1.1 Why a new UHCI driver, we already have one?!?
-
-Correct, but its internal structure got more and more mixed up by the (still
-ongoing) efforts to get isochronous transfers (ISO) to work.
-Since there is an increasing need for reliable ISO-transfers (especially 
-for USB-audio needed by TS and for a DAB-USB-Receiver build by GA and DF), 
-this state was a bit unsatisfying in our opinion, so we've decided (based
-on knowledge and experiences with the old UHCI driver) to start 
-from scratch with a new approach, much simpler but at the same time more 
-powerful.
-It is inspired by the way Win98/Win2000 handles USB requests via URBs,
-but it's definitely 100% free of MS-code and doesn't crash while 
-unplugging an used ISO-device like Win98 ;-)
-Some code for HW setup and root hub management was taken from the 
-original UHCI driver, but heavily modified to fit into the new code.
-The invention of the basic concept, and major coding were completed in two 
-days (and nights) on the 16th and 17th of October 1999, now known as the
-great USB-October-Revolution started by GA, DF, and TS ;-)
-
-Since the concept is in no way UHCI dependent, we hope that it will also be 
-transferred to the OHCI-driver, so both drivers share a common API.
-
-1.2. Advantages and disadvantages
-
-+ All USB transfer types work now!
-+ Asynchronous operation
-+ Simple, but powerful interface (only two calls for start and cancel)
-+ Easy migration to the new API, simplified by a compatibility API
-+ Simple usage of ISO transfers
-+ Automatic linking of requests
-+ ISO transfers allow variable length for each frame and striping
-+ No CPU dependent and non-portable atomic memory access, no asm()-inlines
-+ Tested on x86 and Alpha
-
-- Rewriting for ISO transfers needed
-
-1.3. Is there some compatibility to the old API?
-
-Yes, but only for control, bulk and interrupt transfers. We've implemented 
-some wrapper calls for these transfer types. The usbcore works fine with 
-these wrappers. For ISO there's no compatibility, because the old ISO-API 
-and its semantics were unnecessary complicated in our opinion.
-
-1.4. What's really working?
-
-As said above, CTRL and BULK already work fine even with the wrappers,
-so legacy code wouldn't notice the change.
-Regarding to Thomas, ISO transfers now run stable with USB audio.
-INT transfers (e.g. mouse driver) work fine, too.
-
-1.5. Are there any bugs?
-
-No ;-)
-Hm...
-Well, of course this implementation needs extensive testing on all available
-hardware, but we believe that any fixes shouldn't harm the overall concept.
-
-1.6. What should be done next?
-
-A large part of the request handling seems to be identical for UHCI and 
-OHCI, so it would be a good idea to extract the common parts and have only 
-the HW specific stuff in uhci.c. Furthermore, all other USB device drivers
-should need URBification, if they use isochronous or interrupt transfers.
-One thing missing in the current implementation (and the old UHCI driver) 
-is fair queueing for BULK transfers. Since this would need (in principle) 
-the alteration of already constructed TD chains (to switch from depth to 
-breadth execution), another way has to be found. Maybe some simple 
-heuristics work with the same effect.
-
----------------------------------------------------------------------------
-
-2. Internal structure and mechanisms
-
-To get quickly familiar with the internal structures, here's a short
-description how the new UHCI driver works. However, the ultimate source of
-truth is only uhci.c!
-
-2.1. Descriptor structure (QHs and TDs)
-
-During initialization, the following skeleton is allocated in init_skel:
-
-         framespecific           |           common chain     
-
-framelist[]
-[  0 ]-----> TD --> TD -------\
-[  1 ]-----> TD --> TD --------> TD ----> QH -------> QH -------> QH ---> NULL
-  ...        TD --> TD -------/
-[1023]-----> TD --> TD ------/
-             
-             ^^     ^^           ^^       ^^          ^^          ^^
-   1024 TDs for   7 TDs for    1 TD for   Start of    Start of    End Chain
-            ISO  INT (2-128ms) 1ms-INT    CTRL Chain  BULK Chain
-
-For each CTRL or BULK transfer a new QH is allocated and the containing data
-transfers are appended as (vertical) TDs. After building the whole QH with its
-dangling TDs, the QH is inserted before the BULK Chain QH (for CTRL) or
-before the End Chain QH (for BULK). Since only the QH->next pointers are
-affected, no atomic memory operation is required. The three QHs in the
-common chain are never equipped with TDs!
-
-For ISO or INT, the TD for each frame is simply inserted into the appropriate
-ISO/INT-TD-chain for the desired frame. The 7 skeleton INT-TDs are scattered
-among the 1024 frames similar to the old UHCI driver.
-
-For CTRL/BULK/ISO, the last TD in the transfer has the IOC-bit set. For INT,
-every TD (there is only one...) has the IOC-bit set.
-
-Besides the data for the UHCI controller (2 or 4 32bit words), the descriptors
-are double-linked through the .vertical and .horizontal elements in the 
-SW data of the descriptor (using the double-linked list structures and 
-operations), but SW-linking occurs only in closed domains, i.e. for each of
-the 1024 ISO-chains and the 8 INT-chains there is a closed cycle. This 
-simplifies all insertions and unlinking operations and avoids costly 
-bus_to_virt()-calls.
-
-2.2. URB structure and linking to QH/TDs
-
-During assembly of the QH and TDs of the requested action, these descriptors
-are stored in urb->urb_list, so the allocated QH/TD descriptors are bound to
-this URB.
-If the assembly was successful and the descriptors were added to the HW chain,
-the corresponding URB is inserted into a global URB list for this controller.
-This list stores all pending URBs.
-
-2.3. Interrupt processing
-
-Since UHCI provides no means to directly detect completed transactions, the
-following is done in each UHCI interrupt (uhci_interrupt()):
-
-For each URB in the pending queue (process_urb()), the ACTIVE-flag of the 
-associated TDs are processed (depending on the transfer type 
-process_{transfer|interrupt|iso}()). If the TDs are not active anymore, 
-they indicate the completion of the transaction and the status is calculated. 
-Inactive QH/TDs are removed from the HW chain (since the host controller
-already removed the TDs from the QH, no atomic access is needed) and 
-eventually the URB is marked as completed (OK or errors) and removed from the 
-pending queue. Then the next linked URB is submitted. After (or immediately 
-before) that, the completion handler is called.
-
-2.4. Unlinking URBs
-
-First, all QH/TDs stored in the URB are unlinked from the HW chain. 
-To ensure that the host controller really left a vertical TD chain, we 
-wait for one frame. After that, the TDs are physically destroyed.
-
-2.5. URB linking and the consequences
-
-Since URBs can be linked and the corresponding submit_urb is called in
-the UHCI-interrupt, all work associated with URB/QH/TD assembly has to be
-interrupt save. This forces kmalloc to use GFP_ATOMIC in the interrupt.

+/* The Niagara2 RNG provides a 64-bit read-only random number
+ * register, plus a control register.  Access to the RNG is
+ * virtualized through the hypervisor so that both guests and control
+ * nodes can access the device.
+ *
+ * The entropy source consists of raw entropy sources, each
+ * constructed from a voltage controlled oscillator whose phase is
+ * jittered by thermal noise sources.
+ *
+ * The oscillator in each of the three raw entropy sources run at
+ * different frequencies.  Normally, all three generator outputs are
+ * gathered, xored together, and fed into a CRC circuit, the output of
+ * which is the 64-bit read-only register.
+ *
+ * Some time is necessary for all the necessary entropy to build up
+ * such that a full 64-bits of entropy are available in the register.
+ * In normal operating mode (RNG_CTL_LFSR is set), the chip implements
+ * an interlock which blocks register reads until sufficient entropy
+ * is available.
+ *
+ * A control register is provided for adjusting various aspects of RNG
+ * operation, and to enable diagnostic modes.  Each of the three raw
+ * entropy sources has an enable bit (RNG_CTL_ES{1,2,3}).  Also
+ * provided are fields for controlling the minimum time in cycles
+ * between read accesses to the register (RNG_CTL_WAIT, this controls
+ * the interlock described in the previous paragraph).
+ *
+ * The standard setting is to have the mode bit (RNG_CTL_LFSR) set,
+ * all three entropy sources enabled, and the interlock time set
+ * appropriately.
+ *
+ * The CRC polynomial used by the chip is:
+ *
+ * P(X) = x64 + x61 + x57 + x56 + x52 + x51 + x50 + x48 + x47 + x46 +
+ *        x43 + x42 + x41 + x39 + x38 + x37 + x35 + x32 + x28 + x25 +
+ *        x22 + x21 + x17 + x15 + x13 + x12 + x11 + x7 + x5 + x + 1
+ *
+ * The RNG_CTL_VCO value of each noise cell must be programmed
+ * seperately.  This is why 4 control register values must be provided
+ * to the hypervisor.  During a write, the hypervisor writes them all,
+ * one at a time, to the actual RNG_CTL register.  The first three
+ * values are used to setup the desired RNG_CTL_VCO for each entropy
+ * source, for example:
+ *
+ *      control 0: (1 << RNG_CTL_VCO_SHIFT) | RNG_CTL_ES1
+ *      control 1: (2 << RNG_CTL_VCO_SHIFT) | RNG_CTL_ES2
+ *      control 2: (3 << RNG_CTL_VCO_SHIFT) | RNG_CTL_ES3
+ *
+ * And then the fourth value sets the final chip state and enables
+ * desired.

+ * The Maxim's MAX7301 device is an SPI driven GPIO expander. There are
+ * 28 GPIOs. 8 of them can trigger an interrupt. See datasheet for more
+ * details
+ * Note:
+ * - DIN must be stable at the rising edge of clock.
+ * - when writing:
+ *   - always clock in 16 clocks at once
+ *   - at DIN: D15 first, D0 last
+ *   - D0..D7 = databyte, D8..D14 = commandbyte
+ *   - D15 = low -> write command
+ * - when reading
+ *   - always clock in 16 clocks at once
+ *   - at DIN: D15 first, D0 last
+ *   - D0..D7 = dummy, D8..D14 = register address
+ *   - D15 = high -> read command
+ *   - raise CS and assert it again
+ *   - always clock in 16 clocks at once
+ *   - at DOUT: D15 first, D0 last
+ *   - D0..D7 contains the data from the first cycle
+ *
+ * The driver exports a standard gpiochip interface

+          This driver provides two functions in one configuration:
+          a CDC Ethernet (ECM) link, and a CDC ACM (serial port) link.
+
+          This driver requires four bulk and two interrupt endpoints,
+          plus the ability to handle altsettings.  Not all peripheral
+          controllers are that capable.
+
+          Say "y" to link the driver statically, or "m" to build a

+ *
+ * Because CDC ACM is standardized by the USB-IF, many host operating
+ * systems have drivers for it.  Accordingly, ACM is the preferred
+ * interop solution for serial-port type connections.  The control
+ * models are often not necessary, and in any case don't do much in
+ * this bare-bones implementation.
+ *
+ * Note that even MS-Windows has some support for ACM.  However, that
+ * support is somewhat broken because when you use ACM in a composite
+ * device, having multiple interfaces confuses the poor OS.  It doesn't
+ * seem to understand CDC Union descriptors.  The new "association"
+ * descriptors (roughly equivalent to CDC Unions) may sometimes help.

+ * This function is an RNDIS Ethernet port -- a Microsoft protocol that's
+ * been promoted instead of the standard CDC Ethernet.  The published RNDIS
+ * spec is ambiguous, incomplete, and needlessly complex.  Variants such as
+ * ActiveSync have even worse status in terms of specification.
+ *
+ * In short:  it's a protocol controlled by (and for) Microsoft, not for an
+ * Open ecosystem or markets.  Linux supports it *only* because Microsoft
+ * doesn't support the CDC Ethernet standard.
+ *
+ * The RNDIS data transfer model is complex, with multiple Ethernet packets
+ * per USB message, and out of band data.  The control model is built around
+ * what's essentially an "RNDIS RPC" protocol.  It's all wrapped in a CDC ACM
+ * (modem, not Ethernet) veneer, with those ACM descriptors being entirely
+ * useless (they're ignored).  RNDIS expects to be the only function in its
+ * configuration, so it's no real help if you need composite devices; and
+ * it expects to be the first configuration too.
+ *
+ * There is a single technical advantage of RNDIS over CDC Ethernet, if you
+ * discount the fluff that its RPC can be made to deliver: it doesn't need
+ * a NOP altsetting for the data interface.  That lets it work on some of the
+ * "so smart it's stupid" hardware which takes over configuration changes
+ * from the software, and adds restrictions like "no altsettings".
+ *
+ * Unfortunately MSFT's RNDIS drivers are buggy.  They hang or oops, and
+ * have all sorts of contrary-to-specification oddities that can prevent
+ * them from working sanely.  Since bugfixes (or accurate specs, letting
+ * Linux work around those bugs) are unlikely to ever come from MSFT, you
+ * may want to avoid using RNDIS on purely operational grounds.
+ *
+ * Omissions from the RNDIS 1.0 specification include:
+ *
+ *   - Power management ... references data that's scattered around lots
+ *     of other documentation, which is incorrect/incomplete there too.
+ *
+ *   - There are various undocumented protocol requirements, like the need
+ *     to send garbage in some control-OUT messages.
+ *
+ *   - MS-Windows drivers sometimes emit undocumented requests.

+ * SOURCE/SINK FUNCTION ... a primary testing vehicle for USB peripheral
+ * controller drivers.
+ *
+ * This just sinks bulk packets OUT to the peripheral and sources them IN
+ * to the host, optionally with specific data patterns for integrity tests.
+ * As such it supports basic functionality and load tests.
+ *
+ * In terms of control messaging, this supports all the standard requests
+ * plus two that support control-OUT tests.  If the optional "autoresume"
+ * mode is enabled, it provides good functional coverage for the "USBCV"
+ * test harness from USB-IF.
+ *
+ * Note that because this doesn't queue more than one request at a time,
+ * some other function must be used to test queueing logic.  The network
+ * link (g_ether) is the best overall option for that, since its TX and RX
+ * queues are relatively independent, will receive a range of packet sizes,
+ * and can often be made to run out completely.  Those issues are important
+ * when stress testing peripheral controller drivers.
+ *
+ *
+ * This is currently packaged as a configuration driver, which can't be
+ * combined with other functions to make composite devices.  However, it
+ * can be combined with other independent configurations.

+ * This function packages a simple "CDC Subset" Ethernet port with no real
+ * control mechanisms; just raw data transfer over two bulk endpoints.
+ * The data transfer model is exactly that of CDC Ethernet, which is
+ * why we call it the "CDC Subset".
+ *
+ * Because it's not standardized, this has some interoperability issues.
+ * They mostly relate to driver binding, since the data transfer model is
+ * so simple (CDC Ethernet).  The original versions of this protocol used
+ * specific product/vendor IDs:  byteswapped IDs for Digital Equipment's
+ * SA-1100 "Itsy" board, which could run Linux 2.4 kernels and supported
+ * daughtercards with USB peripheral connectors.  (It was used more often
+ * with other boards, using the Itsy identifiers.)  Linux hosts recognized
+ * this with CONFIG_USB_ARMLINUX; these devices have only one configuration
+ * and one interface.
+ *
+ * At some point, MCCI defined a (nonconformant) CDC MDLM variant called
+ * "SAFE", which happens to have a mode which is identical to the "CDC
+ * Subset" in terms of data transfer and lack of control model.  This was
+ * adopted by later Sharp Zaurus models, and by some other software which
+ * Linux hosts recognize with CONFIG_USB_NET_ZAURUS.
+ *
+ * Because Microsoft's RNDIS drivers are far from robust, we added a few
+ * descriptors to the CDC Subset code, making this code look like a SAFE
+ * implementation.  This lets you use MCCI's host side MS-Windows drivers
+ * if you get fed up with RNDIS.  It also makes it easier for composite
+ * drivers to work, since they can use class based binding instead of
+ * caring about specific product and vendor IDs.

+ * This component encapsulates the TTY layer glue needed to provide basic

+ * After initialization (gserial_setup), these TTY port devices stay

+ * connected to a USB function (gserial_connect), or disconnected (with
+ * gserial_disconnect) when the USB host issues a config change event.
+ * Data can only flow when the port is connected to the host.
+ *
+ * A given TTY port can be made available in multiple configurations.
+ * For example, each one might expose a ttyGS0 node which provides a
+ * login application.  In one case that might use CDC ACM interface 0,
+ * while another configuration might use interface 3 for that.  The
+ * work to handle that (including descriptor management) is not part
+ * of this component.
+ *
+ * Configurations may expose more than one TTY port.  For example, if
+ * ttyGS0 provides login service, then ttyGS1 might provide dialer access
+ * for a telephone or fax link.  And ttyGS2 might be something that just
+ * needs a simple byte stream interface for some messaging protocol that

   Code in this driver inspired by and in a number of places taken
   from Brian Warner's original Keyspan-PDA driver.
 
   This driver has been put together with the support of Innosys, Inc.
   and Keyspan, Inc the manufacturers of the Keyspan USB-serial products.
   Thanks Guys :)

   Thanks to Paulus for miscellaneous tidy ups, some largish chunks
   of much nicer and/or completely new code and (perhaps most uniquely)
   having the patience to sit down and explain why and where he'd changed
-  stuff.

-  Tip 'o the hat to IBM (and previously Linuxcare :) for supporting

+ * the AFAR), and AFSR.UE is cleared by not AFSR.CE, then the AFAR will be unlocked
+ * and ready for another event, even though AFSR.CE is still set.  The same rules
+ * also apply to the M_SYNDROME and E_SYNDROME fields of the AFSR.

+ * mmu_map/unmap are provided by iommu/iounit; Invalid to call on IIep.
+ *
+ * The mmu_map_dma_area establishes two mappings in one go.
+ * These mappings point to pages normally mapped at 'va' (linear address).
+ * First mapping is for CPU visible address at 'a', uncached.
+ * This is an alias, but it works because it is an uncached mapping.
+ * Second mapping is for device visible address, or "bus" address.
+ * The bus address is returned at '*pba'.
+ *
+ * These functions seem distinct, but are hard to split. On sun4c,
+ * at least for now, 'a' is equal to bus address, and retured in *pba.
+ * On sun4m, page attributes depend on the CPU type, so we have to
+ * know if we are mapping RAM or I/O, so it has to be an additional argument
+ * to a separate mapping function for CPU visible mappings.

+/* Sun4v hypervisor interfaces and defines.
+ *
+ * Hypervisor calls are made via traps to software traps number 0x80
+ * and above.  Registers %o0 to %o5 serve as argument, status, and
+ * return value registers.
+ *
+ * There are two kinds of these traps.  First there are the normal
+ * "fast traps" which use software trap 0x80 and encode the function
+ * to invoke by number in register %o5.  Argument and return value
+ * handling is as follows:
+ *
+ * -----------------------------------------------
+ * |  %o5  | function number |     undefined     |
+ * |  %o0  |   argument 0    |   return status   |
+ * |  %o1  |   argument 1    |   return value 1  |
+ * |  %o2  |   argument 2    |   return value 2  |
+ * |  %o3  |   argument 3    |   return value 3  |
+ * |  %o4  |   argument 4    |   return value 4  |
+ * -----------------------------------------------
+ *
+ * The second type are "hyper-fast traps" which encode the function
+ * number in the software trap number itself.  So these use trap
+ * numbers > 0x80.  The register usage for hyper-fast traps is as
+ * follows:
+ *
+ * -----------------------------------------------
+ * |  %o0  |   argument 0    |   return status   |
+ * |  %o1  |   argument 1    |   return value 1  |
+ * |  %o2  |   argument 2    |   return value 2  |
+ * |  %o3  |   argument 3    |   return value 3  |
+ * |  %o4  |   argument 4    |   return value 4  |
+ * -----------------------------------------------
+ *
+ * Registers providing explicit arguments to the hypervisor calls
+ * are volatile across the call.  Upon return their values are
+ * undefined unless explicitly specified as containing a particular
+ * return value by the specific call.  The return status is always
+ * returned in register %o0, zero indicates a successful execution of
+ * the hypervisor call and other values indicate an error status as
+ * defined below.  So, for example, if a hyper-fast trap takes
+ * arguments 0, 1, and 2, then %o0, %o1, and %o2 are volatile across
+ * the call and %o3, %o4, and %o5 would be preserved.
+ *
+ * If the hypervisor trap is invalid, or the fast trap function number
+ * is invalid, HV_EBADTRAP will be returned in %o0.  Also, all 64-bits
+ * of the argument and return values are significant.

+ * to guest termination within a bounded time period.  The platform action
+ * may include recovery actions such as reporting the expiration to a
+ * Service Processor, and/or automatically restarting the gues.
+ *
+ * The 'timeout' parameter is specified in milliseconds, however the
+ * implementated granularity is given by the 'watchdog-resolution'
+ * property in the 'platform' node of the guest's machine description.
+ * The largest allowed timeout value is specified by the
+ * 'watchdog-max-timeout' property of the 'platform' node.
+ *
+ * If the 'timeout' argument is not zero, the watchdog timer is set to
+ * expire after a minimum of 'timeout' milliseconds.
+ *
+ * If the 'timeout' argument is zero, the watchdog timer is disabled.
+ *
+ * If the 'timeout' value exceeds the value of the 'max-watchdog-timeout'
+ * property, the hypervisor leaves the watchdog timer state unchanged,
+ * and returns a status of EINVAL.
+ *
+ * The 'time remaining' return value is valid regardless of whether the
+ * return status is EOK or EINVAL.  A non-zero return value indicates the
+ * number of milliseconds that were remaining until the timer was to expire.
+ * If less than one millisecond remains, the return value is '1'.  If the
+ * watchdog timer was disabled at the time of the call, the return value is
+ * zero.
+ *
+ * If the hypervisor cannot support the exact timeout value requested, but
+ * can support a larger timeout value, the hypervisor may round the actual
+ * timeout to a value larger than the requested timeout, consequently the
+ * 'time remaining' return value may be larger than the previously requested
+ * timeout value.
+ *
+ * Any guest OS debugger should be aware that the watchdog service may be in
+ * use.  Consequently, it is recommended that the watchdog service is
+ * disabled upon debugger entry (e.g. reaching a breakpoint), and then
+ * re-enabled upon returning to normal execution.  The API has been designed
+ * with this in mind, and the 'time remaining' result of the disable call may

+ *
+ *      devino          Device interrupt number.  Specifies the relative

+ *                      For this version of the specification, tsbnum
+ *                      must be zero.

+ *      tsbindex        TSB index.  Identifies which entry in the TSB
+ *                      is used.  The first entry is zero.
+ *
+ *      tsbid           A 64-bit aligned data structure which contains
+ *                      a tsbnum and a tsbindex.  Bits 63:32 contain the
+ *                      tsbnum and bits 31:00 contain the tsbindex.
+ *
+ *                      Use the HV_PCI_TSBID() macro to construct such
+ *                      values.
+ *
+ *      io_attributes   IO attributes for IOMMU mappings.  One of more
+ *                      of the attritbute bits are stores in a 64-bit
+ *                      value.  The values are defined below.
+ *
+ *      r_addr          64-bit real address
+ *
+ *      pci_device      PCI device address.  A PCI device address identifies
+ *                      a specific device on a specific PCI bus segment.
+ *                      A PCI device address ia a 32-bit unsigned integer

+ *
+ *      pci_config_offset
+ *                      PCI configureation space offset.  For conventional
+ *                      PCI a value between 0 and 255.  For extended
+ *                      configuration space, a value between 0 and 4095.
+ *
+ *                      Note: For PCI configuration space accesses, the offset
+ *                            must be aligned to the access size.
+ *
+ *      error_flag      A return value which specifies if the action succeeded
+ *                      or failed.  0 means no error, non-0 means some error
+ *                      occurred while performing the service.
+ *
+ *      io_sync_direction
+ *                      Direction definition for pci_dma_sync(), defined
+ *                      below in HV_PCI_SYNC_*.

+ *
+ *      io_page_list_p  A pointer to an io_page_list.

+ * comparison TAG based upon the virtual address and context which

+ * synchronize while we update the entries.  PTE updates need locking
+ * as well.
+ *
+ * We need to carefully choose a lock bits for the TSB entry.  We

+ * to Greg Onufer for pointing out this performance anomaly.
+ *
+ * Further note that we cannot use the g2, g4, g5, and g7 alternate

+ * arch/sparc64/kernel/etrap.S to see what I mean about g2, and
+ * g4/g5 are the globals which are preserved by etrap processing
+ * for the caller of it.  The g7 register is the return pc for
+ * etrap.  Finally, g6 is the current thread register so we cannot
+ * us it in the spill handlers either.  Most of these rules do not
+ * apply to fill processing, only g6 is not usable.

-/* Sun4v hypervisor interfaces and defines.
- *
- * Hypervisor calls are made via traps to software traps number 0x80
- * and above.  Registers %o0 to %o5 serve as argument, status, and
- * return value registers.
- *
- * There are two kinds of these traps.  First there are the normal
- * "fast traps" which use software trap 0x80 and encode the function
- * to invoke by number in register %o5.  Argument and return value
- * handling is as follows:
- *
- * -----------------------------------------------
- * |  %o5  | function number |     undefined     |
- * |  %o0  |   argument 0    |   return status   |
- * |  %o1  |   argument 1    |   return value 1  |
- * |  %o2  |   argument 2    |   return value 2  |
- * |  %o3  |   argument 3    |   return value 3  |
- * |  %o4  |   argument 4    |   return value 4  |
- * -----------------------------------------------
- *
- * The second type are "hyper-fast traps" which encode the function
- * number in the software trap number itself.  So these use trap
- * numbers > 0x80.  The register usage for hyper-fast traps is as
- * follows:
- *
- * -----------------------------------------------
- * |  %o0  |   argument 0    |   return status   |
- * |  %o1  |   argument 1    |   return value 1  |
- * |  %o2  |   argument 2    |   return value 2  |
- * |  %o3  |   argument 3    |   return value 3  |
- * |  %o4  |   argument 4    |   return value 4  |
- * -----------------------------------------------
- *
- * Registers providing explicit arguments to the hypervisor calls
- * are volatile across the call.  Upon return their values are
- * undefined unless explicitly specified as containing a particular
- * return value by the specific call.  The return status is always
- * returned in register %o0, zero indicates a successful execution of
- * the hypervisor call and other values indicate an error status as
- * defined below.  So, for example, if a hyper-fast trap takes
- * arguments 0, 1, and 2, then %o0, %o1, and %o2 are volatile across
- * the call and %o3, %o4, and %o5 would be preserved.
- *
- * If the hypervisor trap is invalid, or the fast trap function number
- * is invalid, HV_EBADTRAP will be returned in %o0.  Also, all 64-bits
- * of the argument and return values are significant.

- *
- * A guest uses this API to set a watchdog timer.  Once the gues has set
- * the timer, it must call the timer service again either to disable or
- * postpone the expiration.  If the timer expires before being reset or
- * disabled, then the hypervisor take a platform specific action leading
- * to guest termination within a bounded time period.  The platform action
- * may include recovery actions such as reporting the expiration to a
- * Service Processor, and/or automatically restarting the gues.
- *
- * The 'timeout' parameter is specified in milliseconds, however the
- * implementated granularity is given by the 'watchdog-resolution'
- * property in the 'platform' node of the guest's machine description.
- * The largest allowed timeout value is specified by the
- * 'watchdog-max-timeout' property of the 'platform' node.
- *
- * If the 'timeout' argument is not zero, the watchdog timer is set to
- * expire after a minimum of 'timeout' milliseconds.
- *
- * If the 'timeout' argument is zero, the watchdog timer is disabled.
- *
- * If the 'timeout' value exceeds the value of the 'max-watchdog-timeout'
- * property, the hypervisor leaves the watchdog timer state unchanged,
- * and returns a status of EINVAL.
- *
- * The 'time remaining' return value is valid regardless of whether the
- * return status is EOK or EINVAL.  A non-zero return value indicates the
- * number of milliseconds that were remaining until the timer was to expire.
- * If less than one millisecond remains, the return value is '1'.  If the
- * watchdog timer was disabled at the time of the call, the return value is
- * zero.
- *
- * If the hypervisor cannot support the exact timeout value requested, but
- * can support a larger timeout value, the hypervisor may round the actual
- * timeout to a value larger than the requested timeout, consequently the
- * 'time remaining' return value may be larger than the previously requested
- * timeout value.
- *
- * Any guest OS debugger should be aware that the watchdog service may be in
- * use.  Consequently, it is recommended that the watchdog service is
- * disabled upon debugger entry (e.g. reaching a breakpoint), and then
- * re-enabled upon returning to normal execution.  The API has been designed
- * with this in mind, and the 'time remaining' result of the disable call may
- * be used directly as the timeout argument of the re-enable call.

- *
- * Terminology:
- *
- *      cpuid           Unique opaque value which represents a target cpu.
- *
- *      devhandle       Device handle.  It uniquely identifies a device, and
- *                      consistes of the lower 28-bits of the hi-cell of the
- *                      first entry of the device's "reg" property in the
- *                      OBP device tree.
- *
- *      devino          Device interrupt number.  Specifies the relative
- *                      interrupt number within the device.  The unique
- *                      combination of devhandle and devino are used to
- *                      identify a specific device interrupt.
- *
- *                      Note: The devino value is the same as the values in the
- *                            "interrupts" property or "interrupt-map" property
- *                            in the OBP device tree for that device.
- *
- *      sysino          System interrupt number.  A 64-bit unsigned interger
- *                      representing a unique interrupt within a virtual
- *                      machine.
- *
- *      intr_state      A flag representing the interrupt state for a given
- *                      sysino.  The state values are defined below.
- *
- *      intr_enabled    A flag representing the 'enabled' state for a given

-/* PCI IO services.
- *
- * See the terminology descriptions in the device interrupt services
- * section above as those apply here too.  Here are terminology
- * definitions specific to these PCI IO services:
- *
- *      tsbnum          TSB number.  Indentifies which io-tsb is used.
- *                      For this version of the specification, tsbnum
- *                      must be zero.
- *
- *      tsbindex        TSB index.  Identifies which entry in the TSB
- *                      is used.  The first entry is zero.
- *
- *      tsbid           A 64-bit aligned data structure which contains
- *                      a tsbnum and a tsbindex.  Bits 63:32 contain the
- *                      tsbnum and bits 31:00 contain the tsbindex.
- *
- *                      Use the HV_PCI_TSBID() macro to construct such
- *                      values.
- *
- *      io_attributes   IO attributes for IOMMU mappings.  One of more
- *                      of the attritbute bits are stores in a 64-bit
- *                      value.  The values are defined below.
- *
- *      r_addr          64-bit real address
- *
- *      pci_device      PCI device address.  A PCI device address identifies
- *                      a specific device on a specific PCI bus segment.
- *                      A PCI device address ia a 32-bit unsigned integer
- *                      with the following format:
- *
- *                              00000000.bbbbbbbb.dddddfff.00000000
- *
- *                      Use the HV_PCI_DEVICE_BUILD() macro to construct
- *                      such values.
- *
- *      pci_config_offset
- *                      PCI configureation space offset.  For conventional
- *                      PCI a value between 0 and 255.  For extended
- *                      configuration space, a value between 0 and 4095.
- *
- *                      Note: For PCI configuration space accesses, the offset
- *                            must be aligned to the access size.
- *
- *      error_flag      A return value which specifies if the action succeeded
- *                      or failed.  0 means no error, non-0 means some error
- *                      occurred while performing the service.
- *
- *      io_sync_direction
- *                      Direction definition for pci_dma_sync(), defined
- *                      below in HV_PCI_SYNC_*.
- *
- *      io_page_list    A list of io_page_addresses, an io_page_address is
- *                      a real address.
- *
- *      io_page_list_p  A pointer to an io_page_list.
- *
- *      "size based byte swap" - Some functions do size based byte swapping
- *                               which allows sw to access pointers and
- *                               counters in native form when the processor

- *                               IO bus.  Size-based byte swapping converts a
- *                               multi-byte field between big-endian and
- *                               little-endian format.

- * was one instruction after the branch delay slot and the chip still hung.
- * The offending sequence was the following in sym_wakeup_done() of the

- *
- *      call    sym_ccb_from_dsa, 0
- *       movge  %icc, 0, %l0

- *
- * The branch has to be mispredicted for the bug to occur.  Therefore, we put

- * delay slot to avoid the problem case.

-/* The sparc64 TSB is similar to the powerpc hashtables.  It's a
- * power-of-2 sized table of TAG/PTE pairs.  The cpu precomputes
- * pointers into this table for 8K and 64K page sizes, and also a
- * comparison TAG based upon the virtual address and context which
- * faults.
- *
- * TLB miss trap handler software does the actual lookup via something
- * of the form:
- *
- *      ldxa            [%g0] ASI_{D,I}MMU_TSB_8KB_PTR, %g1
- *      ldxa            [%g0] ASI_{D,I}MMU, %g6
- *      sllx            %g6, 22, %g6
- *      srlx            %g6, 22, %g6
- *      ldda            [%g1] ASI_NUCLEUS_QUAD_LDD, %g4
- *      cmp             %g4, %g6
- *      bne,pn  %xcc, tsb_miss_{d,i}tlb
- *       mov            FAULT_CODE_{D,I}TLB, %g3
- *      stxa            %g5, [%g0] ASI_{D,I}TLB_DATA_IN
- *      retry
- *
- *
- * Each 16-byte slot of the TSB is the 8-byte tag and then the 8-byte
- * PTE.  The TAG is of the same layout as the TLB TAG TARGET mmu
- * register which is:
- *
- * -------------------------------------------------
- * |  -  |  CONTEXT |  -  |    VADDR bits 63:22    |
- * -------------------------------------------------
- *  63 61 60      48 47 42 41                     0
- *
- * But actually, since we use per-mm TSB's, we zero out the CONTEXT
- * field.
- *
- * Like the powerpc hashtables we need to use locking in order to
- * synchronize while we update the entries.  PTE updates need locking
- * as well.
- *
- * We need to carefully choose a lock bits for the TSB entry.  We
- * choose to use bit 47 in the tag.  Also, since we never map anything
- * at page zero in context zero, we use zero as an invalid tag entry.
- * When the lock bit is set, this forces a tag comparison failure.

- *
- * For the user cases we used to use the %asi register, but
- * it turns out that the "wr xxx, %asi" costs ~5 cycles, so
- * now we use immediate ASI loads and stores instead.  Kudos
- * to Greg Onufer for pointing out this performance anomaly.
- *
- * Further note that we cannot use the g2, g4, g5, and g7 alternate
- * globals in the spill routines, check out the save instruction in
- * arch/sparc64/kernel/etrap.S to see what I mean about g2, and
- * g4/g5 are the globals which are preserved by etrap processing
- * for the caller of it.  The g7 register is the return pc for
- * etrap.  Finally, g6 is the current thread register so we cannot

+ * struct usb_function - describes one function of a configuration
+ * @name: For diagnostics, identifies the function.
+ * @strings: tables of strings, keyed by identifiers assigned during bind()
+ *      and by language IDs provided in control requests
+ * @descriptors: Table of full (or low) speed descriptors, using interface and
+ *      string identifiers assigned during @bind().  If this pointer is null,
+ *      the function will not be available at full speed (or at low speed).
+ * @hs_descriptors: Table of high speed descriptors, using interface and
+ *      string identifiers assigned during @bind().  If this pointer is null,
+ *      the function will not be available at high speed.
+ * @config: assigned when @usb_add_function() is called; this is the
+ *      configuration with which this function is associated.
+ * @bind: Before the gadget can register, all of its functions bind() to the
+ *      available resources including string and interface identifiers used
+ *      in interface or class descriptors; endpoints; I/O buffers; and so on.
+ * @unbind: Reverses @bind; called as a side effect of unregistering the
+ *      driver which added this function.
+ * @set_alt: (REQUIRED) Reconfigures altsettings; function drivers may
+ *      initialize usb_ep.driver data at this time (when it is used).
+ *      Note that setting an interface to its current altsetting resets
+ *      interface state, and that all interfaces have a disabled state.
+ * @get_alt: Returns the active altsetting.  If this is not provided,
+ *      then only altsetting zero is supported.
+ * @disable: (REQUIRED) Indicates the function should be disabled.  Reasons
+ *      include host resetting or reconfiguring the gadget, and disconnection.
+ * @setup: Used for interface-specific control requests.
+ * @suspend: Notifies functions when the host stops sending USB traffic.
+ * @resume: Notifies functions when the host restarts USB traffic.
+ *
+ * A single USB function uses one or more interfaces, and should in most
+ * cases support operation at both full and high speeds.  Each function is
+ * associated by @usb_add_function() with a one configuration; that function
+ * causes @bind() to be called so resources can be allocated as part of
+ * setting up a gadget driver.  Those resources include endpoints, which
+ * should be allocated using @usb_ep_autoconfig().
+ *
+ * To support dual speed operation, a function driver provides descriptors
+ * for both high and full speed operation.  Except in rare cases that don't
+ * involve bulk endpoints, each speed needs different endpoint descriptors.
+ *
+ * Function drivers choose their own strategies for managing instance data.
+ * The simplest strategy just declares it "static', which means the function
+ * can only be activated once.  If the function needs to be exposed in more
+ * than one configuration at a given speed, it needs to support multiple
+ * usb_function structures (one for each configuration).
+ *
+ * A more complex strategy might encapsulate a @usb_function structure inside
+ * a driver-specific instance structure to allows multiple activations.  An
+ * example of multiple activations might be a CDC ACM function that supports
+ * two or more distinct instances within the same configuration, providing
+ * several independent logical data links to a USB host.

+ * Before returning from @bind, various fields in the template descriptor

+ * @config: the currently active configuration

+ * One of these devices is allocated and initialized before the

+ * This revision of the gadget framework should probably try to make
+ * sure doing that won't hurt too much.
+ *
+ * One notion for how to handle Wireless USB devices involves:
+ * (a) a second gadget here, discovery mechanism TBD, but likely
+ *     needing separate "register/unregister WUSB gadget" calls;
+ * (b) updates to usb_gadget to include flags "is it wireless",
+ *     "is it wired", plus (presumably in a wrapper structure)
+ *     bandgroup and PHY info;
+ * (c) presumably a wireless_ep wrapping a usb_ep, and reporting
+ *     wireless-specific parameters like maxburst and maxsequence;
+ * (d) configurations that are specific to wireless links;
+ * (e) function drivers that understand wireless configs and will
+ *     support wireless for (additional) function instances;
+ * (f) a function to support association setup (like CBAF), not
+ *     necessarily requiring a wireless adapter;
+ * (g) composite device setup that can create one or more wireless
