  drm/radeon: Don't move pinned BOs
  drm/radeon: add a dpm quirk for all R7 370 parts
  drm/radeon: add another R7 370 quirk

         Choose this option to enable ACP IP support for AMD SOCs.
+        This adds the ACP (Audio CoProcessor) IP driver and wires
+        it up into the amdgpu driver.  The ACP block provides the DMA
+        engine for the i2s-based ALSA driver. It is required for audio
+        on APUs which utilize an i2s codec.
