2016-01-11ASoC: AMD: Add missing include fileGuenter Roeck1-0/+1
arm:allmodconfig, s390:allmodconfig, sparc64:allmodconfig, and probably other builds fail with sound/soc/amd/acp-pcm-dma.c:83:2: error: implicit declaration of function ‘readl’ sound/soc/amd/acp-pcm-dma.c:88:2: error: implicit declaration of function ‘writel’ Include linux/io.h explicitly to fix the problem.

2016-01-10ASoC: AMD: Manage ACP 2.x SRAM banks powerMaruthi Srinivas Bayyavarapu1-7/+87
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.

2016-01-10ASoC: AMD: add pm opsMaruthi Srinivas Bayyavarapu1-0/+48
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.

2016-01-10ASoC: AMD: add AMD ASoC ACP 2.x DMA driverMaruthi Srinivas Bayyavarapu4-0/+1039
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.
