[PATCH] amdgpu acp support drm-fixes-4.5

[Alex Deucher]

Hi Dave,

These patches add ACP support to amdgpu.  I would have sent these in
for the merge window but they depended on audio and pm tree changes
that all went upstream in 4.5 so they were not available in the drm
tree at the time.  Chances of regressions are low since this just
adds support for a new hw block.  It does not modify any existing
functionality.  This enables audio on CZ asics which use i2s audio
rather than azalia audio.

The following changes since commit d8b8eb829d4c30cd1e41a1ddc308a0e7c22169da:

  Merge branch 'drm-rockchip-next-fixes-2016-01-22' of https://github.com/markyzq/kernel-drm-rockchip into drm-fixes (2016-01-29 10:04:29 +1000)
