+GPIO controllers on MPC8xxx SoCs
+
+This is for the non-QE/CPM/GUTs GPIO controllers as found on
+8349, 8572, 8610 and compatible.
+
+Every GPIO controller node must have #gpio-cells property defined,
+this information will be used to translate gpio-specifiers.
+
+Required properties:
+- compatible : "fsl,<CHIP>-gpio" followed by "fsl,mpc8349-gpio" for
+  83xx, "fsl,mpc8572-gpio" for 85xx and "fsl,mpc8610-gpio" for 86xx.
+- #gpio-cells : Should be two. The first cell is the pin number and the
+  second cell is used to specify optional parameters (currently unused).
+ - interrupts : Interrupt mapping for GPIO IRQ (currently unused).
+ - interrupt-parent : Phandle for the interrupt controller that
+   services interrupts for this device.
+- gpio-controller : Marks the port as GPIO controller.
+
+Example of gpio-controller nodes for a MPC8347 SoC:
+
+        gpio1: gpio-controller@c00 {
+                #gpio-cells = <2>;
+                compatible = "fsl,mpc8347-gpio", "fsl,mpc8349-gpio";
+                reg = <0xc00 0x100>;
+                interrupts = <74 0x8>;
+                interrupt-parent = <&ipic>;
+                gpio-controller;
+        };
+
+        gpio2: gpio-controller@d00 {
+                #gpio-cells = <2>;
+                compatible = "fsl,mpc8347-gpio", "fsl,mpc8349-gpio";

+
+Notes on fsl,playback-dma and fsl,capture-dma:
+
+On SOCs that have an SSI, specific DMA channels are hard-wired for playback
+and capture.  On the MPC8610, for example, SSI1 must use DMA channel 0 for
+playback and DMA channel 1 for capture.  SSI2 must use DMA channel 2 for
+playback and DMA channel 3 for capture.  The developer can choose which
+DMA controller to use, but the channels themselves are hard-wired.  The
+purpose of these two properties is to represent this hardware design.
+
+The device tree nodes for the DMA channels that are referenced by
+"fsl,playback-dma" and "fsl,capture-dma" must be marked as compatible with
+"fsl,ssi-dma-channel".  The SOC-specific compatible string (e.g.
+"fsl,mpc8610-dma-channel") can remain.  If these nodes are left as
+"fsl,elo-dma-channel" or "fsl,eloplus-dma-channel", then the generic Elo DMA
+drivers (fsldma) will attempt to use them, and it will conflict with the
+sound drivers.

-                 Information about /proc/ppc_htab
-=====================================================================
-
-This document and the related code was written by me (Cort Dougan), please
-email me (cort@fsmlabs.com) if you have questions, comments or corrections.
-
-Last Change: 2.16.98
-
-This entry in the proc directory is readable by all users but only
-writable by root.
-
-The ppc_htab interface is a user level way of accessing the
-performance monitoring registers as well as providing information
-about the PTE hash table.
-
-1. Reading
-
-  Reading this file will give you information about the memory management
-  hash table that serves as an extended tlb for page translation on the
-  powerpc.  It will also give you information about performance measurement
-  specific to the cpu that you are using.
-
-  Explanation of the 604 Performance Monitoring Fields:
-    MMCR0 - the current value of the MMCR0 register
-    PMC1
-    PMC2 - the value of the performance counters and a
-           description of what events they are counting
-           which are based on MMCR0 bit settings.
-  Explanation of the PTE Hash Table fields:
-
-    Size - hash table size in Kb.
-    Buckets -  number of buckets in the table.
-    Address - the virtual kernel address of the hash table base.
-    Entries - the number of ptes that can be stored in the hash table.
-    User/Kernel - how many pte's are in use by the kernel or user at that time.
-    Overflows - How many of the entries are in their secondary hash location.
-    Percent full - ratio of free pte entries to in use entries.
-    Reloads - Count of how many hash table misses have occurred
-              that were fixed with a reload from the linux tables.
-              Should always be 0 on 603 based machines.
-    Non-error Misses - Count of how many hash table misses have occurred
-              that were completed with the creation of a pte in the linux
-              tables with a call to do_page_fault().
-    Error Misses - Number of misses due to errors such as bad address
-              and permission violations.  This includes kernel access of
-              bad user addresses that are fixed up by the trap handler.
-
-  Note that calculation of the data displayed from /proc/ppc_htab takes
-  a long time and spends a great deal of time in the kernel.  It would
-  be quite hard on performance to read this file constantly.  In time
-  there may be a counter in the kernel that allows successive reads from
-  this file only after a given amount of time has passed to reduce the
-  possibility of a user slowing the system by reading this file.
-
-2. Writing
-
-  Writing to the ppc_htab allows you to change the characteristics of
-  the powerpc PTE hash table and setup performance monitoring.
-
-  Resizing the PTE hash table is not enabled right now due to many
-  complications with moving the hash table, rehashing the entries
-  and many many SMP issues that would have to be dealt with.
-
-  Write options to ppc_htab:
-  
-   - To set the size of the hash table to 64Kb:
-
-      echo 'size 64' > /proc/ppc_htab
-
-     The size must be a multiple of 64 and must be greater than or equal to
-     64.
-
-   - To turn off performance monitoring:
-
-      echo 'off' > /proc/ppc_htab
-
-   - To reset the counters without changing what they're counting:
-
-      echo 'reset' > /proc/ppc_htab
-
-     Note that counting will continue after the reset if it is enabled.
-
-   - To count only events in user mode or only in kernel mode:
-
-      echo 'user' > /proc/ppc_htab
-       ...or...
-      echo 'kernel' > /proc/ppc_htab
-
-     Note that these two options are exclusive of one another and the
-     lack of either of these options counts user and kernel.
-     Using 'reset' and 'off' reset these flags.
-
-   - The 604 has 2 performance counters which can each count events from
-     a specific set of events.  These sets are disjoint so it is not
-     possible to count _any_ combination of 2 events.  One event can
-     be counted by PMC1 and one by PMC2.
-
-     To start counting a particular event use:
-
-      echo 'event' > /proc/ppc_htab
-
-     and choose from these events:
-
-     PMC1
-     ----
-      'ic miss' - instruction cache misses
-      'dtlb' - data tlb misses (not hash table misses)
-
-     PMC2
-     ----
-      'dc miss' - data cache misses
-      'itlb' - instruction tlb misses (not hash table misses)
-      'load miss time' - cycles to complete a load miss
-
-3. Bugs
-
-  The PMC1 and PMC2 counters can overflow and give no indication of that
-  in /proc/ppc_htab.

-    on this machine will be done shortly.
-
-    The code makes the assumption of only two processors.  The changes

-    I don't have any machines with >2 processors so it's not high on my

-  BeBox
-    BeBox support hasn't been added to the 2.1.X kernels from 2.0.X
-    but work is being done and SMP support for BeBox is in the works.

-  CHRP
-    CHRP SMP works and is fairly solid.  It's been tested on the IBM F50
-    with 4 processors for quite some time now.

- * Basic four-word fraction declaration and manipulation.
- *
- * When adding quadword support for 32 bit machines, we need
- * to be a little careful as double multiply uses some of these
- * macros: (in op-2.h)
- * _FP_MUL_MEAT_2_wide() uses _FP_FRAC_DECL_4, _FP_FRAC_WORD_4,
- * _FP_FRAC_ADD_4, _FP_FRAC_SRS_4
- * _FP_MUL_MEAT_2_gmp() uses _FP_FRAC_SRS_4 (and should use
- * _FP_FRAC_DECL_4: it appears to be broken and is not used
- * anywhere anyway. )
- *
- * I've now fixed all the macros that were here from the sparc64 code.
- * [*none* of the shift macros were correct!] -- PMM 02/1998
- *
- * The only quadword stuff that remains to be coded is:
- * 1) the conversion to/from ints, which requires
- * that we check (in op-common.h) that the following do the right thing
- * for quadwords: _FP_TO_INT(Q,4,r,X,rsz,rsg), _FP_FROM_INT(Q,4,X,r,rs,rt)
- * 2) multiply, divide and sqrt, which require:
- * _FP_MUL_MEAT_4_*(R,X,Y), _FP_DIV_MEAT_4_*(R,X,Y), _FP_SQRT_MEAT_4(R,S,T,X,q),
- * This also needs _FP_MUL_MEAT_Q and _FP_DIV_MEAT_Q to be defined to
- * some suitable _FP_MUL_MEAT_4_* macros in sfp-machine.h.
- * [we're free to choose whatever FP_MUL_MEAT_4_* macros we need for
- * these; they are used nowhere else. ]

+ * 7     RO PEX8548 Interrupt Status
+ * 6     RO Reserved

+ * 2     RO AXIS Message FIFO B Interrupt Status
+ * 1     RO AXIS Message FIFO C Interrupt Status

+ *
+ * Interrupts can be forwarded to one of two output lines. Nothing
