This patch set is split from 2 patch. And used with master SOF FW.
All applied to topic/sof-v4.14 as is, will squash later this week. I just verified that with the SOF/SOFT master + this kernel branch the playback progresses at the normal speed and I see data + bitclock on SSP5 on the Up2. Still have to figure out why the frame sync is silent.
