Timur Tabi 9cb6abcb26 powerpc/8xxx: remove 85xx/86xx restrictions from fsl_guts.h
Remove the check for CONFIG_PPC_85xx and CONFIG_PPC_86xx from fsl_guts.h.
The check was originally intended to allow the same header file to
be used on 85xx and 86xx systems, even though the Global Utilities
register could be different.  It turns out that they're not actually
different, and so the check is not necessary.  In addition, neither
macro is defined for 64-bit e5500 kernels, so that causes a build
break.

Timur Tabi 70ac07bb63 ASoC: fsl: p1022ds: tell the WM8776 codec driver that it's the master
The WM8776 codec driver requires the machine driver to set one of the
SND_SOC_DAIFMT_CBx_xxx values.  The P1022DS machine driver should be setting
SND_SOC_DAIFMT_CBM_CFM, but since that value was zero, no one noticed.

Commit 75d9ac46 ("ASoC: Allow DAI formats to be specified in the
dai_link"), however, changed the value of SND_SOC_DAIFMT_CBM_CFM from zero
to a non-zero value, which means that it now needs to be specifically set
by the machine driver.

We also set SND_SOC_DAIFMT_NB_NF, for the same reason.

Shawn Guo 2b81ec6914 ASoC: fsl: check property 'compatible' for the machine name
Check /compatible rather than /model to determine the machine name.
The p1022ds older device trees get a different /model from the new
ones, while /compatible is consistent there, so checking /compatible
will save the bother of detecting older p1022ds device trees.

Align mpc8610_hpcd with p1022_ds on getting codec node by just calling

exporting get_node_by_phandle_name() when we consolidate the common

shared by more machine drivers added later.

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.

Lars-Peter Clausen 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 =

Timur Tabi 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.

the device.  Instead, we should claim the IRQ when the device is probed.

Julia Lawall 880b8ffd45 ASoC: pl022_ds.c: Add of_node_put to avoid memory leak
Add a call to of_node_put in the error handling code following a call to
of_parse_phandle.

This patch also moves the existing call to of_node_put tothe end of the
error handling code, to make it possible to jump to of_node_put without
doing the other cleanup operations.  These appear to be disjoint
operations, so the ordering doesn't matter.

The semantic match that finds this problem is as follows:

Timur Tabi 38fec7272b ASoC: mpc8610: replace of_device with platform_device
'struct of_device' no longer exists, and its functionality has been merged
into platform_device.  Update the MPC8610 HPCD audio drivers (fsl_ssi, fsl_dma,
and mpc8610_hpcd) accordingly.

Also add a #include for slab.h, which is now needed for kmalloc and kfree.

Timur Tabi 27ef3744f8 ASoC: add support for the Freescale P1022 DS reference board
The Freescale P1022 is a dual-core e500-based SOC with multimedia capabilities,
specifically the same SSI audio controller on the MPC8610.  The P1022 DS
reference board includes a P1022 and a Wolfson Microelectronics WM8776
codec.

Timur Tabi c04019d450 ASoC: add support for separate codec DAIs to the fsl_dma driver
Some codecs have separate DAIs for playback and capture, so the DMA driver
should allocate a DMA buffer only for the streams that are valid when the
driver is opened.
