From 9246539bdda4206c53be1045778b642f1c8137e4 Mon Sep 17 00:00:00 2001 From: Jarkko Nikula Date: Mon, 11 Aug 2014 14:15:37 +0300 Subject: 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().
