The dai_dmic_update_bits() function is used in start trigger code dai_dmic_start() and in capture runtime to control DMIC IP in unmute sequence. Especially the start sequence is timing critical so it's better not produce additional delay in this function.

This patch removes the traces printed inside spinlock protected code. The DMIC capture start code is timing critical. Traces leave an unknown delay into start sequence, so it's better to not produce them. Signed-off-by: Seppo Ingalsuo <[email protected]> (cherry picked from commit 78920e8) Signed-off-by: Kai Vehmanen <[email protected]>
The unreset of ACE PDM controllers is moved to beginning of void dai_dmic_start() and done side-by-side. This change is done for adhering to recommended hardware initialization flow to avoid intermittent failures on ARL-S.
