How about this?

Having FSL_SSI/FSL_SPDIF, but not SND_SOC_IMX_PCM_DMA does not make sense on 
iMX.
So how about:

	select SND_SOC_IMX_PCM_DMA if SND_IMX_SOC

and remove all the other 'select SND_SOC_IMX_PCM_DMA' statements. That's in 
my opinion much nicer.

Yes, makes sense. Should I do another version of the patch?

Yes. The patch should also add a select for SND_SOC_IMX_PCM_FIQ as that is 
used in the same way in the fsl_ssi driver. If anybody is afraid that 
selecting both SND_SOC_IMX_PCM_FIQ and SND_SOC_IMX_PCM_DMA by default adds 
too much overhead you could add boolean sub-options that allow to 
enable/disable support individually.

Yes, the overhead should be negligable since the FIQ code is tiny.
Arnd, please CC maintainers on patches - you've sent this to my
Linaro address again and not added Liam.
