Dan Carpenter	a65ecc4070	drm/amd: cleanup get_mfd_cell_dev() ... It's simpler to just use snprintf() to print this to one buffer instead of using strcpy() and strcat(). Also using snprintf() is slightly safer than using sprintf().

Maruthi Srinivas Bayyavarapu	25030321ba	drm/amd: add pm domain for ACP IP sub blocks ... ACP IP have internal DMA controller, DW I2S controller and DSPs as separate power tiles. DMA and I2S devices are added to generic pm domain, so that entire IP can be powered off/on at appropriate times. Unused DSPs are made to be powered off though they are powered on during ACP pm domain power on sequence.

Maruthi Bayyavarapu	a8fe58cec3	drm/amd: add ACP driver support ... This adds the ACP (Audio CoProcessor) IP driver and wires it up to the amdgpu driver. The ACP block provides the DMA engine for i2s based ALSA driver. This is required for audio on APUs that utilize an i2s codec.
