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:
