1c433fbda4 [ALSA] soc - 0.13 ASoC headers
This patch updates the API's to include the new DAI configuration and
clocking architecture.
Changes:-
 o Removed DAI automatic matching and capabilities structure (struct
snd_soc_dai_mode) and macros.
 o Added DAI operations for codec and CPU interfaces.
 o Removed config_sysclk() function and struct snd_soc_clock_info. No
longer needed as clocking is now configured manually in the machine
drivers. Also removed other clocking data from structures.
 o Updated version to 0.13
 o Added shift to SOC_SINGLE_EXT kcontrol macro.

4484bb2e93 [ALSA] Fix the soc code after dhowells workqueue changes.
From: Andrew Morton <akpm@osdl.org>
I converted the workqueues to per-device while I was there.  It seems
strange to create a new kernel thread (on each CPU!) and to then only
have a single global work to ever be queued upon it.
Plus without this, I'd have to use the _NAR stuff, gawd help me.
Does that workqueue really need to be per-cpu?
Does that workqueue really need to exist?  Why not use keventd?

a71a468a50 [ALSA] ASoC: Add support for BCLK based on (Rate * Chn * Word Size)
This patch adds support for the DAI BCLK to be generated by multiplying
Rate * Channels * Word Size (RCW).
This now gives 3 options for BCLK clocking and synchronisation :-
 1. BCLK = Rate * x
 2. BCLK = MCLK / x
 3. BCLK = Rate * Chn * Word Size.  (New)
Changes:-
 o Add support for RCW generation of BCLK
 o Update Documentation to include RCW.
 o Update DAI documentation for label = value DAI modes.
 o Add RCW support to wm8731, wm8750 and pxa2xx-i2s drivers.
