[alsa-devel] [PATCH 2/4] ASoC: fsl: separate SSI and DMA Kconfig options

[Shawn Guo]

The fsl_ssi driver will possibly be shared between Freescale PowerPC
and ARM/IMX families, so give it a separate Kconfig option.  Then
fsl_ssi driver can possibly be selected independently from selecting
PowerPC DMA based PCM driver.
