Applied patch 1/2.
max channels should be 16 for BYT, HSW, APL and CNL given that the SSP port can playback 16 channels.

Are you sure of this? I checked the SSP's register for CNL: SSTSA and SSRSA. It only supports 8-channel.
You and Pierre are right (it's 8), I was looking at a recent driver patch that had the wrong value.
