Subject: ASoC: amd: ps: add acp_reset flag check in acp pci driver pm ops.
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=198c93e2fc0b74ae520393118d7cb02762c04bf3;p=linux.git

ASoC: amd: ps: add acp_reset flag check in acp pci driver pm ops.

AMD SoundWire manager supports different power modes.
acp_reset flag will be set to false only when SoundWire manager power
mode is selected as ClockStop Mode. For rest of the combinations
(ACP PDM + SDW), acp_reset flag will be set to true.
When acp_reset flag is set, acp de-init and acp init sequence should
be invoked during suspend/resume callbacks.
