ALSA SoC drivers should be specify SND_SOC_AC97_BUS instead, not AC97_BUS.
Without SND_SOC_AC97_BUS defined, an AC97 device will not get correctly
registered on the AC97 bus, which prevents thinks like the WM9712
touchscreen driver from getting probed.

Tested against 2.6.31-rc1.

These drivers use spin_event_timeout() which is only present in the
PowerPC tree at present and which is undergoing some API revisions
so temporarily mark them as BROKEN until these issues are sorted
out.

I've implemented retries for when the AC97 hardware doesn't reset on
first try. About 10% of the time both the Efika and pcm030 AC97 codecs
don't reset on first try and need to be poked multiple times.  Failure
is indicated by not having the link clock start ticking. Every once in
a while even five pokes won't get the link started and I have to power
cycle.

The CS4270 supports stand-alone mode, where the codec is not connect to the
I2C or SPI buses.  Instead, input voltages configure the codec at power-on.
The CS4270 ASoC device driver has partial support for this mode, but the
code was never tested, and partial support doesn't help anyone.  It also made
the rest of the code more complicated than necessary.

Change the Kconfig and Makefile options for Freescale MPC8610 audio drivers

so that only the platform is selected.

Also fix the naming of the driver files to conform to ALSA standards.

The dependency on SND_SOC is already fulfilled in sound/soc/Kconfig,
thus no more need in Kconfig of each sub directory.

Without this patch it is possible to select drivers which require
bestcomm support without bestcomm support being selected.  This
patch reworks the bestcomm dependencies to ensure the correct
bestcomm tasks are always enabled.

Simple utility layer for creating ASoC machine instances based on data
in the OpenFirmware device tree.  OF aware platform drivers and codec
drivers register themselves with this framework and the framework
automatically instantiates a machine driver.  At the moment, the driver
is not very capable and it is expected to be extended as more features
are needed for specifying the configuration in the device tree.

This is most likely temporary glue code to work around limitations in
the ASoC v1 framework.  When v2 is merged, most of this driver will
need to be reworked.
