Subject: ASoC: Intel: Wait Baytrail ADSP boot at resume_early stage
X-Git-Tag: firefly_0821_release~176^2~3158^2~21^2^5~1
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=9246539bdda4206c53be1045778b642f1c8137e4;p=firefly-linux-kernel-4.4.55.git
ASoC: Intel: Wait Baytrail ADSP boot at resume_early stage
Remove sst_byt_pcm_dev_resume() and move waiting of firmware boot into
sst_byt_pcm_dev_resume_early(). Now suspend_late and resume_early phases are
in sync with each other so that we know that ADSP was put into reset and was
unpowered after suspend_late and is ready to resume IO after resume_early
during resume stage in sst_byt_pcm_trigger().
