The chip errata for the i.MX35, Rev.2 has the following errata:
ENGcm06222: SSI:Transmission does not take place in bit length early frame sync
configuration
The workaround states, that TX_EN and SSI_EN bits should be set in the same
register write. As the next errata in the document (ENGcm06532) says to always
write RX_EN and TX_EN in the same register write in network mode.
Therefore include the whole write to
CCSR_SSI_SCR_TE and CCSR_SSI_SCR_RE
into the write to
CCSR_SSI_SCR_SSIEN

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.

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.

The code enabled SSIEN when triggered by SNDRV_PCM_TRIGGER_START,
so move the disable code to SNDRV_PCM_TRIGGER_STOP for symmetric.
This also allows us to use the SSI driver more flexible so that
it can support some use cases like "aplay S16_LE.wav S24_LE.wav"
which would call the driver in sequence like:
startup()->hw_params(S16_LE)->trigger(START)->tirgger(STOP)->
hw_params(S24_LE)->trigger(START)->tirgger(STOP)->shutdown()
If we disable SSIEN in shutdown(), the second hw_params() would
bypass the sample bits setting while using symmetric_rate.

Some more fixes and enhancements, and also a bunch of refectoring for
AC'97 support which enables more than one AC'97 controller driver to be

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.
