documentation. This patch adds those changes to the documentation.

cd7f0295aa ASoC: fsl-ssi: ac97-slave support
This patch adds ac97-slave support.

For ac97, the registers have to be setup earlier than for other ssi
modes because there is some communication with the external device
before streaming. So this patch introduces a fsl_ssi_setup function to
setup the registers for different ssi operation modes seperately.

This patch was tested with imx27-pca100.

3a5e517bb2 ASoC: fsl-ssi: Use generic DMA bindings if possible
There may be some platforms using fsl-ssi that do not have a DMA driver
with generic DMA bindings. So this patch adds support for the generic
DMA bindings, while still accepting the old "fsl,dma-events" property if
"dmas" is not found.

de623ece5b ASoC: fsl-ssi: Add support for imx-pcm-fiq
Add support for non-dma pcm for imx platforms with imx-pcm-fiq support.
Instead of imx-pcm-audio, in this case imx-pcm-fiq-audio device is added
and the SIER flags are set differently.

We need imx-pcm-fiq for some boards that use an incompatible codec.
imx-pcm-fiq handles those codecs differently and allows to operate with
them. DMA is not possible because some data sent by the codecs, e.g.
wm9712, is not in the datastream. Also some data is mixed up in the
fifos, so that we need to sort them out manually.

624dcbdea2 ASoC: fsl: Move fsl-ssi binding doc to sound/
fsl-ssi was located in powerpc/fsl/ssi.txt. This is no powerpc specific
device, so it should be moved to sound/ as it connects to differen audio
codecs.
