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.

Remove unneeded error handling on the result of a call to
platform_get_resource_byname when the value is passed to devm_ioremap_resource.

In the case of omap-dmic.c, the error-handling code of
devm_ioremap_resource is also corrected to include releasing the clock.

A simplified version of the semantic patch that makes this change is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@@
expression pdev,res,e,e1;
expression ret != 0;
identifier l;
@@

  res = platform_get_resource_byname(...);
- if (res == NULL) { ... \(goto l;\|return ret;\) }
  e = devm_ioremap_resource(e1, res);

in a later patch. It's just there to make the transition more readable.

The Tegra30 I2S driver was writing the AHUB interface parameters to the
playback path register rather than the capture path register. This
caused the capture parameters not to be configured at all, so if
capturing using non-HW-default parameters (e.g. 16-bit stereo rather
than 8-bit mono) the audio would be corrupted.

With this fixed, audio capture from an analog microphone works correctly
on the Cardhu board.
