3.10-stable review patch. If anyone has any objections, please let me know.
------------------ From: Alex Deucher <alexander.deuc...@amd.com> commit 58d327da9721f7a0f6e46c8dfa5cc5546fd7078a upstream. These asics seem to use a mix of the DCE2.x and DCE3.2 audio interfaces despite what the register spec says.
