ASoC: AMD: Manage ACP 2.x SRAM banks power2016-01-10T12:44:13+00:00Maruthi Srinivas BayyavarapuMaruthi.Bayyavarapu@amd.com2016-01-08T23:22:11+00:00urn:sha1:c36d9b3f6de7c6aefed5fdf6ad752773bdafa60c
ACP SRAM banks gets turned on when ACP is powered on.
Not all banks are used for playback/capture. So, power on
required banks during audio device open and power off during
audio device close.

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.

ACP IP has internal DMA controller with multiple channels which
can be programmed in cyclic/non cyclic manner. ACP can generate
interrupt upon completion of DMA transfer, if required.
The PCM driver provides the platform DMA component to ALSA core.
