From 00e4c3b6e285da90e736fbefff3d9e74a200ee54 Mon Sep 17 00:00:00 2001 From: Charles Keepax Date: Tue, 18 Nov 2014 16:25:27 +0000 Subject: ASoC: wm_adsp: Move core_ena to be co-located with start bit Many firmwares do not wait for the start bit before they begin processing audio, whilst this is a bug on the firmware side there are too many such firmwares in the wild to ignore the situation. This patch moves the core enable to happen at same time as the start, the firmware looses the ability to overlap its own startup with the audio path bring up but we ensure that all firmwares behave.
