-Subject: [PATCH 03/17] ASoC: AMD: add pm ops
-
-genpd will power off/on ACP to manage runtime ACP PM. ACP runtime PM
-hooks are added to get it deinitialized and initialized respectively,
-after it is powered off/on.
-
-When system goes to suspend when audio usecase is active, ACP will
-be powered off through genpd. When it resumes, ACP needs to be
-initialized and reconfigured.
