c7a507eea1 ASoC: fsi: fixup SND_SOC_DAIFMT_CBx_CFx flags
SND_SOC_DAIFMT_CBx_CFx means "codec" side master/slave mode.
Then, FSI will be master mode if it was SND_SOC_DAIFMT_CBS_CFS.

This patch fixup platform settings too.
Then, it tidyups SND_SOC_DAIFMT_INV settings.

23a735cc02 ASoC: migor: Convert to table based DAPM setup
Use table based setup to register the DAPM widgets and routes.  This on one hand
makes the code a bit shorter and cleaner and on the other hand the board level
DAPM elements get registered in the card's DAPM context rather than in the
CODEC's DAPM context.

ba9c949f79 ASoC: rsnd: rename scu to src
R-Car sound has SCU unit which has SRC/CTU/MIX/DVC,
and current rsnd driver has scu.c and scu module.

My first concept was control these feature on scu.c

R-Car sound DAI consists from SSI/SCU/SSIU/SRU...

a7ddf151b0 ASoC: sh: Don't set unused struct snd_pcm_hardware fields
The ASoC core assumes that the PCM component of the ASoC card transparently
moves data around and does not impose any restrictions on the memory layout or
the transfer speed. It ignores all fields from the snd_pcm_hardware struct for
the PCM driver that are related to this. Setting these fields in the PCM driver
might suggest otherwise though, so rather not set them.

92eba04e4b ASoC: rcar: remove RSND_SSI_CLK_FROM_ADG
R-Car sound has clock pin for each SSI, and sometimes,
these pins are shared with paired SSI.
It may sometimes become "SSI-A clock pin is master" and
"SSI-B clock pin is slave", but "SSI-A/B clock pins are shared".
SSI-B needs SSI-A clock in this case.

Current R-Car sound driver is using RSND_SSI_xxx flag
to control this kind of shared pin behavior.

But, this information, especially clock master setting,
can be got from ASoC set_fmt settings.
This patch removes rsnd_ssi_mode_init() and extend rsnd_ssi_mode_set()
to controlling pin settings via .set_fmt.

This patch doesn't removes RSND_SSI_CLK_FROM_ADG flag at this point
to avoid conflict branch merging between ASoC <-> SH-ARM.

b047e1cce8 ASoC: ac97: Support multi-platform AC'97
Currently we can only have a single platform built in with AC'97 support
due to the use of a global variable to provide the bus operations. Fix
this by making that variable a pointer and having the bus drivers set the
operations prior to registering.

This is not a particularly good or nice approach but it avoids blocking
multiplatform and a real fix involves fixing the fairly deep problems
with AC'97 support - we should be converting it to a real bus.

siu_dai.c is using snd_soc_register_dais(),

OTOH, new API snd_soc_register_component() uses properly
snd_soc_register_dai()  (henceforth dai()) or
snd_soc_register_dais() (henceforth dais()) via num_dai.
Then, cpu_dai_name will be "siu-i2s-dai" if dais() was used,
and it will be "siu-pcm-audio" if dai() was used.
Therefore this patch fixup migor_dai :: cpu_dai_name too.

ab6f6d8521 ASoC: fsi: add master clock control functions
Current FSI driver required set_rate() platform callback function
to set audio clock if it was master mode,
because it seemed that CPG/FSI-DIV clocks calculation depend on
platform/board/cpu.
But it was calculable regardless of platform.
This patch supports audio clock calculation method,
but the sampling rate under 32kHz is not supported at this point.
Old type set_rate() is still supported now,
but it will be deleted on next version

80b4addc9c ASoC: fsi: care fsi_hw_start/stop() return value
Current FSI driver didn't care fsi_hw_start/stop() return value,
and it causes WARNING() call if SNDRV_PCM_TRIGGER_START failed.
This patch solved this issue

ddeb2d701b ASoC: fsi: fsi_set_master_clk() was called from fsi_hw_xxx() only
Current FSI driver is using fsi_set_master_clk() if it needs system clock.
But this function was called from
fsi_hw_shutdown()/fsi_dai_trigger()/fsi_resume() without a sense of unity.
Because of this, sound playback after suspend failed sometimes.
To keep consistency, fsi_master_clk() was called from
fsi_hw_start/stop() only now.

57451e4377 ASoC: fsi: don't reschedule DMA from an atomic context
shdma doesn't support transfer re-scheduling or triggering from callbacks
or from atomic context. The fsi driver issues DMA transfers from a tasklet
context, which is a bug. To fix it convert tasklet to a work.

struct fsi_master *master became member of struct fsi_priv from

(ASoC: sh_fsi: avoid using global variable)

So, master = NULL is not necessary on fsi_probe() now.
