When usbfs receives a ctrl-request from userspace it calls check_ctrlrecip,
which for a request with USB_RECIP_ENDPOINT tries to map this to an interface
to see if this interface is claimed, except for ctrl-requests with a type of
USB_TYPE_VENDOR.
When trying to use this device: http://www.akaipro.com/eiepro
redirected to a Windows vm running on qemu on top of Linux.
The windows driver makes a ctrl-req with USB_TYPE_CLASS and
USB_RECIP_ENDPOINT with index 0, and the mapping of the endpoint (0) to
the interface fails since ep 0 is the ctrl endpoint and thus never is
part of an interface.
This patch fixes this ctrl-req failing by skipping the checkintf call for
USB_RECIP_ENDPOINT ctrl-reqs on the ctrl endpoint.

Reduce the size of the objects by consolidating
the duplicated USB_STORAGE into a single function.
Add function usb_stor_dbg to emit debugging messages.
Always validate the format and arguments.
Reduce the number of uses of CONFIG_USB_STORAGE_DEBUG.
Reduces size of objects ~7KB when CONFIG_USB_STORAGE_DEBUG
is set.

We remove the redundant tdi_reset in ehci_setup since there
is already it in ehci_reset.
It was observed that the duplicated tdi_reset was causing
the PHY_CLK_VALID bit unstable.

The definitions have moved to include/linux/usb/samsung-usb-phy.h,
and plat/usb-phy.h is unavailable from drivers in a multiplatform
configuration.
Also fix up the plat/usb-phy.h header file to use the definitions
from the new header instead of providing a separate copy.

Wishbone is an open hardware SoC bus commonly used in FPGA
designs. Bus access can be serialized using the Etherbone
protocol <http://www.ohwr.org/projects/etherbone-core>.
This driver is intended to be used with devices which attach
their internal Wishbone bus to a USB serial interface using
the Etherbone protocol. A userspace library is required to
speak the protocol made available by this driver as ttyUSBx.

Just like the OHCI counter part we just can remove the architecture
specific symbols which prevent these configuration symbols from being
selected by platforms/architectures requiring it. The original
implementation did not scale at all since it required each and every
single architecture to be added for these configuration symbols to be
selected. Now it is up to the EHCI driver and/or platform to select
these configuration symbols accordingly.

This patch removes the depends on USB from all config symbols in
drivers/usb/host/Kconfig and replace that with an if USB / endif block
as suggested by Alan Stern. Some source ... Kconfig lines have been
shuffled around to permit a better regroupment of the Kconfig files
depending on "config USB" item. No functionnal change is introduced.

7edb3da: (USB: EHCI: make ehci-s5p a separate driver)
raised an issue with ehci-s5p's driver data.
Now that 's5p_ehci_hcd' doesn't maintain pointer to 'usb_hcd'
and s5p_ehci is nothing but a pointer to hcd->priv;
add hcd to the driver data rather than s5p_ehci.
This fixes issues with null pointer dereferencing in
s5p_ehci_shutdown(), s5p_ehci_suspend(), s5p_ehci_resume().

xHCI misc cleanup patches for 3.10
Hi Greg,
Here's three cleanup patches for 3.10. Nothing big here, just some debugging
output changes, a macro rename, and a math macro change that should have no
behavioral effects.
Tested on the Intel Panther Point xHCI host, with USB storage and mouse, with
xHCI debugging turned on. I don't have the TI host that causes the debugging
output changes to trigger.

There are no functional changes in this patch. However, because the
compliance mode timer can be deleted in more than one function, it
seemed expedient to include the function name in the debug strings.
Also limited the use of capitals to the first word in the compliance
mode debug messages, except after a function name where all words
start with lower case, in keeping with the style prevalent elsewhere
in xhci.c.

Use ilog2() rather than __ffs() for calculating SEGMENT_SHIFT as ilog2() can
be worked out at compile time, whereas __ffs() must be calculated at runtime.

Separate the Qualcomm QSD/MSM on-chip host controller driver from
ehci-hcd host code so that it can be built as a separate driver module.
This work is part of enabling multi-platform kernels on ARM;
however, note that other changes are still needed before Qualcomm QSD/MSM
can be booted with a multi-platform kernel, which is not expected before
3.11.
With the infrastructure added by Alan Stern in patch 3e0232039
"USB: EHCI: prepare to make ehci-hcd a library module", we can
avoid this problem by turning a bus glue into a separate
module, as we do here for the msm bus glue.
In V5 (arnd):
- add FIXME about missing usb_add_hcd() or usb_remove_hcd() calls
In V3:
- Detailed commit message added here describing why this patch is required.
- Arranged #include's in alphabetical order.
- driver.name initialized hcd_name[] = "ehci-msm" in platform_driver
structure initialization instead of "msm-ehci", which was the reason
why it broke in EHCI USB testing
In V2:
Tegra patch related changes removed from this patch.

This work is part of enabling multi-platform kernels on ARM;
however, note that other changes are still needed before Atmel can be
booted with a multi-platform kernel. This is currently planned for
Linux-3.11.
With the infrastructure added by Alan Stern in patch 3e0232039
"USB: EHCI: prepare to make ehci-hcd a library module", we can
avoid this problem by turning a bus glue into a separate
module, as we do here for the Atmel bus glue.
In V4 (arnd):
- reordered #include statements.
- removed call to ehci_shutdown and the corresponding export
In V3:
- Detailed commit message added here about why this patch is required.
- Replaced hcd_name string "ehci-atmel" to "atmel-ehci".
- Inserted blank line in the Makefile to separate the EHCI drivers from
the following non-EHCI drivers.
- Exported ehci_shutdown symbol as it is needed by the Atmel driver.
- Eliminated ehci_atmel_setup routine because hcd registers
can be directly set in the ehci_atmel_drv_probe function.
In V2:
Resolved below compiler error.
drivers/usb/host/ehci-atmel.c: In function 'ehci_atmel_drv_remove':
drivers/usb/host/ehci-atmel.c:167: error: implicit declaration of function 'ehci_shutdown'

Separate the Samsung S5P/EXYNOS host controller driver from ehci-hcd
host code so that it can be built as a separate driver module.
This work is part of enabling multi-platform kernels on ARM;
however, note that other changes are still needed before S5P/EXYNOS can
be booted with a multi-platform kernel. We currently expect those
to get merged for 3.10.
With the infrastructure added by Alan Stern in patch 3e0232039
"USB: EHCI: prepare to make ehci-hcd a library module", we can
avoid this problem by turning a bus glue into a separate
module, as we do here for the s5p bus glue.
In V4 (arnd)
- revert some of the pointless changes.
- fix allocation of s5p specific data structure.
In V3:
- Detailed commit message added here, why this patch is required.
- MODULE_LICENSE is GPL v2.
- Added .extra_priv_size to eliminate the separate allocation of
the s5p_ehci_hcd structure and removed .reset function pointer
initialization.
- Arranged #include's in alphabetical order.
- After using extra_priv_size initialization, struct usb_hcd *hcd
is redundant and can be removed from the probe function.
- Eliminated s5p_ehci_phy_enable,contents of statements moved
into the s5p_ehci_probe
- Eliminated s5p_ehci_phy_disable, contents of statements moved into
the s5p_ehci_remove.
In V2:
- Tegra patch related changes removed from this patch.

Separate the SPEAr host controller driver from ehci-hcd host code
so that it can be built as a separate driver module.
This work is part of enabling multi-platform kernels on ARM;
however, note that other changes are still needed before SPEAr can be
booted with a multi-platform kernel, but they are queued in the
arm-soc tree for 3.10.
With the infrastructure added by Alan Stern in patch 3e0232039
"USB: EHCI: prepare to make ehci-hcd a library module", we can
avoid this problem by turning a bus glue into a separate
module, as we do here for the SPEAr bus glue.
In V4 (arnd):
- renamed all 'struct spear_ehci' pointers from 'ehci' to the
less ambiguous 'sehci'.
- folded trivial spear_start_ehci/spear_stop_ehci functions into
callers.
- brought back initialization of ehci->caps.
In V3:
- Detailed commit message added here about why this patch is required.
- Eliminated ehci_spear_setup routine because hcd registers can
be directly set in the spear_ehci_hcd_drv_probe function.
- spear_overrides struct initialized.
- Converted to using .extra_priv_size for allocating spear_ehci,
and updated all users of that structure.
- to_spear_ehci() macro modified for spear_ehci.
In V2:
- Replaced spear as SPEAr everywhere, leaving functions/variables/config options.

Separate the Orion host controller driver from ehci-hcd host
code into its own driver module because of following reason.
With the multiplatform changes in arm-soc tree, it becomes
possible to enable the mvebu platform (which uses
ehci-orion) at the same time as other platforms that require
a conflicting EHCI bus glue. At the moment, this results
in a warning like
drivers/usb/host/ehci-hcd.c:1297:0: warning: "PLATFORM_DRIVER" redefined [enabled by default]
drivers/usb/host/ehci-hcd.c:1277:0: note: this is the location of the previous definition
drivers/usb/host/ehci-orion.c:334:31: warning: 'ehci_orion_driver' defined but not used [-Wunused-variable]
and an ehci driver that only works on one of them.
With the infrastructure added by Alan Stern in patch 3e0232039
"USB: EHCI: prepare to make ehci-hcd a library module", we can
avoid this problem by turning a bus glue into a separate
module, as we do here for the orion bus glue.
An earlier version of this patch was included in 3.9 but caused
a regression there, which has subsequently been fixed.
While we are here, use the opportunity to disabiguate the two
Marvell EHCI controller implementations in Kconfig.
In V4 (arnd):
- Improve Kconfig text
In V3:
- More detail provided in commit message regarding this patch.
- Replaced hcd_name string "ehci-orion" into "orion-ehci".
- MODULE_LICENSE is GPL v2.
- In ehci_init_driver calling second argument passed as NULL instead of
ehci_orion_overrides because ehci_orion_overrides is removed.
In V2:
- Tegra patch related changes removed from this patch.

usb: patches for v3.10 merge window
Here is the big Gadget & PHY pull request. Many of us have
been really busy lately getting multiple drivers to a better
position.
Since this pull request is so large, I will divide it in sections
so it's easier to grasp what's included.
- cleanups:
. UDC drivers no longer touch gadget->dev, that's now udc-core
responsibility
. Many more UDC drivers converted to usb_gadget_map/unmap_request()
. UDC drivers no longer initialize DMA-related fields from gadget's
device structure
. UDC drivers don't touch gadget.dev.driver directly
. UDC drivers don't assign gadget.dev.release directly
. Removal of some unused DMA_ADDR_INVALID
. Introduction of CONFIG_USB_PHY
. All phy drivers have been moved to drivers/usb/phy and renamed to
a common naming scheme
. Fix PHY layer so it never returns a NULL pointer, also fix all
callers to avoid using IS_ERR_OR_NULL()
. Sparse fixes all over the place
. drivers/usb/otg/ has been deleted
. Marvel drivers (mv_udc, ehci-mv, mv_otg and mv_u3d) improved clock
usage
- new features:
. UDC core now provides a generic way for tracking and reporting
UDC's state (not attached, resuming, suspended, addressed,
default, etc)
. twl4030-usb learned that it shouldn't be enabled during init
. Full DT support for DWC3 has been implemented
. ab8500-usb learned about pinctrl framework
. nop PHY learned about DeviceTree and regulators
. DWC3 learned about suspend/resume
. DWC3 can now be compiled in host-only and gadget-only (as well as
DRD) configurations
. UVC now enables streaming endpoint based on negotiated speed
. isp1301 now implements the PHY API properly
. configfs-based interface for gadget drivers which will lead to
the removal of all code which just combines functions together
to build functional gadget drivers.
. f_serial and f_obex were converted to new configfs interface while
maintaining old interface around.
- non-critical fixes:
. UVC gadget driver got fixes for Endpoint usage and stream calculation
. ab8500-usb fixed unbalanced clock and regulator API usage
. twl4030-usb got a fix for when OMAP3 is booted with cable connected
. fusb300_udc got a fix for DMA usage
. UVC got fixes for two assertions of the USB Video Class Compliance
specification revision 1.1
. build warning issues caused by recent addition of __must_check to
regulator API
These are all changes which deserve a mention, all other changes are related
to these one or minor spelling fixes and other similar tasks.

recent changes to gadget framework have
exposed a flaw in nokia.c where it uses
f_ecm.c but it wasn't including it like
other gadget drivers.
This is a temporary patch until all other
function drivers are converted to new API
where each function driver becomes a module
and binding is done through configfs.

Converting f_obex to the new function interface requires converting
the f_obex's function code and its users.
This patch converts the f_obex.c to the new function interface.
The file is now compiled into a separate usb_f_obex.ko module.
The old function interface is provided by means of preprocessor
conditional directives. After all users are converted, the old interface
can be removed.

There are no old function interface users left, so the old interface
can be removed.

Converting f_serial to the new function interface requires converting
the f_serial's function code and its users.
This patch converts the f_serial.c to the new function interface.
The file is now compiled into a separate usb_f_serial.ko module.
The old function interface is provided by means of preprocessor
conditional directives. After all users are converted, the old interface
can be removed.

f_serial.c isn't necessary in nokia.c, we can

In order to convert to configfs the USB functions need to be converted
to the new interface from Sebastian, which also requires turning them
into separate modules. Some of these modules will consist of just
one object file, e.g. f_ncm.o. But some of the modules will eventually
consist of more than one object file, e.g. for mass storage there
will be f_mass_storage.o and storage_common.o. The resulting module
cannot be called f_mass_storage.ko due to cyclic dependency. This patch
introduces a naming scheme for the said resulting modules:
usb_f_xxxxxx.ko
e.g. usb_f_mass_storage.ko, usb_f_ss_lb.ko, usb_f_rndis.ko etc.

v5…v6
- wired up strings with usb_gstrings_attach()
- add UDC attribe. Write "udc-name" will bind the gadget. Write an empty
string (it should contain \n since 0 bytes write get optimzed away)
will unbind the UDC from the gadget. The name of available UDCs can be
obtained from /sys/class/udc/
v4…v5
- string rework. This will add a strings folder incl. language code like
strings/409/manufacturer
as suggested by Alan.
- rebased ontop reworked functions.c which has usb_function_instance
which is used prior after "mkdir acm.instance" and can be directly
used for configuration via configfs.
v3…v4
- moved functions from the root folde down to the gadget as suggested
by Michał
- configs have now their own configs folder as suggested by Michał.
The folder is still name.bConfigurationValue where name becomes the
sConfiguration. Is this usefull should we just stilc
configs/bConfigurationValue/ ?
- added configfs support to the ACM function. The port_num attribute is
exported by f_acm. An argument has been added to the USB alloc
function to distinguish between "old" (use facm_configure() to
configure and configfs interface (expose a config_node).
The port_num is currently a dumb counter. It will
require some function re-work to make it work.
scheduled for v5:
- sym linking function into config.
v2…v3
- replaced one ifndef by ifdef as suggested by Micahał
- strstr()/strchr() function_make as suggested by Micahł
- replace [iSerialNumber|iProduct|iManufacturer] with
[sSerialNumber|sProduct|sManufacturer] as suggested by Alan
- added creation of config descriptors
v1…v2
- moved gadgets from configfs' root directory into /udcs/ within our
"usb_gadget" folder. Requested by Andrzej & Michał
- use a dot as a delimiter between function's name and its instance's name
as suggested by Michał
- renamed all config_item_type, configfs_group_operations, make_group,
drop_item as suggested by suggested by Andrzej to remain consisten
within this file and within other configfs users
- Since configfs.c and functions.c are now part of the udc-core module,
the module itself is now called udc. Also added a tiny ifdef around
init code becuase udc-core is subsys init and this is too early for
configfs in the built-in case. In the module case, we can only have
one init function.

It possible to allocate the tty port number within the "instance"
structure of the function and there is no need to expose this
information within the gadget and therefore it is removed here.
This patch converts only f_acm and all its users. The other gadgets will
follow once the function is converted to the function interface.

the u_ether.c file has a global variable named the_dev which keeps a
pointer to the network device after it has been created via
gether_setup_name(). It is only used internally by u_ether. This patches
moves the variable to its users and passes it via the port.ioport where
it is saved later anyway.

This patch converts the acm_ms gadget to make use of the function
framework to request the ACM function.
The "old" include interface for acm is now removed since nokia was the
last user of it (for ACM).

ab8500_usb_delayed_work was implemented as a workaroud for the internal
only and now unsupported v1.0 version of AB850. This patch removes the
delayed work and just leave a link status update call at probe time.

Amend the ab8500-usb driver to optionally take a pin control handle and
set the state of the pins to "default" on ab8500_usb_phy_enable and to
"sleep" on ab8500_usb_phy_disable.
The pinctrl handle is released on ab8500_usb_phy_disable because USB
pins are shared with ab8505_micro_usb_iddet driver.

Fix last ab->phy.notifier call to use vbus_draw as notifier argument, as
that's used in ab8500_charger to control charging current.
Also drop a related TODO comment, and the additional
ux500_musb_set_vbus(musb, 0), as with this patch it was causing an
erratic behaviour of gadget ep0 state machine.

To prevent clock and regulator frameworks from complaining, only disable
the host or peripheral phy if they were enabled.
