[alsa-devel] [PATCH 1/7] ASoC: Intel: Add Baytrail SST ID and Baytrail specific register bits

[Jarkko Nikula]

While the SHIM register addresses in Baytrail are the same than Haswell and
Broadwell their register size is 64-bit and some bits are different.

This patch adds the SST device ID for Baytrail and Baytrail specific
SHIM bit definitions.
