From 198c93e2fc0b74ae520393118d7cb02762c04bf3 Mon Sep 17 00:00:00 2001 From: Vijendar Mukunda Date: Mon, 12 Jun 2023 15:29:03 +0530 Subject: 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.
