4c3c5df05e ASoC: fsl: Add .owner to struct snd_soc_card
Missed .owner of struct snd_soc_card will prevent the module from being

6132725eac ASoC: fsl/powerpc: don't rely on the cell-index property
Instead of using the 'cell-index' property in the I2C adapter node to
determine the adapter number, just query the i2c_adapter object directly.

Previously, the I2C nodes always appeared in cell-index order, so the
dynamic numbering coincided with the cell-index property.  With commit
ab827d97 ("powerpc/85xx: Rework P1022DS device tree"), the I2C nodes are
unintentionally reversed in the device tree, and so the machine driver
guesses the wrong I2C adapter number.

a806aa9207 ASoC: p1022ds: add support for fsl,P1022 and fsl,P1022DS model names
Commit ab827d97 ("powerpc/85xx: Rework P1022DS device tree") renamed the
the /model property of the P1022DS device tree from "fsl,P1022" to
"fsl,P1022DS".  To support both old and new device trees, the ASoC
machine driver for the P1022DS needs to query the /model property and
update the platform driver object dynamically.

85e7652d89 ASoC: Constify snd_soc_dai_ops structs
Commit 1ee46ebd("ASoC: Make the DAI ops constant in the DAI structure")
introduced the possibility to have constant DAI ops structures, yet this is
barley used in both existing drivers and also new drivers being submitted,
although none of them modifies its DAI ops structure. The later is not
surprising since existing drivers are often used as templates for new drivers.
So this patch just constifies all existing snd_soc_dai_ops structs to eliminate
the issue altogether.

The patch was generated with the following coccinelle semantic patch:
// <smpl>

identifier ops;
@@
-struct snd_soc_dai_ops ops =
+const struct snd_soc_dai_ops ops =
{ ... };

5e538ecade ASoC: improve asynchronous mode support in the fsl_ssi driver
The Freescale SSI audio controller supports "synchronous" and "asynchronous"
modes.  In synchronous mode, playback and capture use the same input clock,
so sample rates must be the same during simultaneous playback and capture.
Unfortunately, the code which supports asynchronous mode is just broken in
various ways.  In particular, it was constraining sample sizes as well as
the sample rate.

The fix also allows us to simplify the code by eliminating the 'asynchronous',
'playback', and 'capture' variables that were used to keep track of playback
and capture streams.

Unfortunately, it turns out that simulataneous playback and record does not
actually work on the only platform that supports asynchronous mode: the
Freescale P1022DS reference board.  If a second stream is started, the SSI
grinds to halt for both streams.  This is true even if the P1022 is configured
for synchronous mode, so it's likely a hardware problem that needs to be
worked around.

1fab6cafc7 ASoC: claim the IRQ when the fsl_ssi device is probed, not opened
The PowerPC Freescale SSI driver is claiming the IRQ when the IRQ when
the device is opened, which means that the /proc/interrupts entry for
the SSI exists only during playback or capture.  This also meant that
the user won't know that the IRQ number is wrong until he tries to use
the device.  Instead, we should claim the IRQ when the device is probed.

8e9d869028 asoc/multi-component: fsl: add support for variable SSI FIFO depth
Add code that programs the DMA and SSI controllers differently based on the
FIFO depth of the SSI.

The SSI devices on the MPC8610 and the P1022 are identical in every way except
one: the transmit and receive FIFO depth.  On the MPC8610, the depth is eight.
On the P1022, it's fifteen.  The device tree nodes for the SSI include a
"fsl,fifo-depth" property that specifies the FIFO depth.

ff71334a46 asoc/multi-component: fsl: add support for disabled SSI nodes
Add support for adding "status = disabled" to an SSI node to incidate that it
is not wired on the board.  This replaces the not-so-intuitive previous method
of omitting a codec-handle property.

87a0632b29 asoc/multi-component: fsl: fix exit and error paths in DMA and SSI drivers
The error handling code in the OF probe function of the SSI driver is not
freeing all resources correctly.

Since the machine driver no longer calls the DMA driver to provide information
about the SSI, we don't need to keep a list of DMA objects any more.  In
addition, the fsl_soc_dma_remove() function is incorrectly removing *all*
DMA objects when it should only remove one.

1a3c5a491a asoc/multi-component: fsl: add support for 36-bit physical addresses
Update the DMA driver used by the Freescale MPC8610 HPCD audio driver to
support 36-bit physical addresses, for both DMA buffers and the SSI registers.

The DMA driver calls snd_dma_alloc_pages() to allocate the DMA buffers for
playback and capture.  This function is just a front-end for
dma_alloc_coherent().  Currently, dma_alloc_coherent() only allocates buffers
in low memory (it ignores GFP_HIGHMEM), so we never actually get a DMA buffer
with a real 36-bit physical address.

6e6f66226f powerpc: rename immap_86xx.h to fsl_guts.h, and add 85xx support
The immap_86xx.h header file only defines one data structure: the "global
utilities" register set found on Freescale PowerPC SOCs.  Rename this file
to fsl_guts.h to reflect its true purpose, and extend it to cover the "GUTS"
register set on 85xx chips.

f0fba2ad1b ASoC: multi-component - ASoC Multi-Component Support
This patch extends the ASoC API to allow sound cards to have more than one
CODEC and more than one platform DMA controller. This is achieved by dividing
some current ASoC structures that contain both driver data and device data into
structures that only either contain device data or driver data. i.e.

 struct snd_soc_codec    --->  struct snd_soc_codec (device data)
                          +->  struct snd_soc_codec_driver (driver data)

 struct snd_soc_platform --->  struct snd_soc_platform (device data)
                          +->  struct snd_soc_platform_driver (driver data)

 struct snd_soc_dai      --->  struct snd_soc_dai (device data)
                          +->  struct snd_soc_dai_driver (driver data)

 struct snd_soc_device   --->  deleted

This now allows ASoC to be more tightly aligned with the Linux driver model and
also means that every ASoC codec, platform and (platform) DAI is a kernel
device. ASoC component private data is now stored as device private data.

The ASoC sound card struct snd_soc_card has also been updated to store lists
of it's components rather than a pointer to a codec and platform. The PCM
runtime struct soc_pcm_runtime now has pointers to all its components.

This patch adds DAPM support for ASoC multi-component and removes struct
snd_soc_socdev from DAPM core. All DAPM calls are now made on a card, codec
or runtime PCM level basis rather than using snd_soc_socdev.

Other notable multi-component changes:-

 * Stream operations now de-reference less structures.
 * close_delayed work() now runs on a DAI basis rather than looping all DAIs
   in a card.
 * PM suspend()/resume() operations can now handle N CODECs and Platforms
   per sound card.
 * Added soc_bind_dai_link() to bind the component devices to the sound card.
 * Added soc_dai_link_probe() and soc_dai_link_remove() to probe and remove
   DAI link components.
 * sysfs entries can now be registered per component per card.
 * snd_soc_new_pcms() functionailty rolled into dai_link_probe().
 * snd_soc_register_codec() now does all the codec list and mutex init.

This patch changes the probe() and remove() of the CODEC drivers as follows:-

 o Make CODEC driver a platform driver
 o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core.
 o Removed all static codec pointers (drivers now support > 1 codec dev)
 o snd_soc_register_pcms() now done by core.
 o snd_soc_register_dai() folded into snd_soc_register_codec().
