drm/radeon: UVD bringup v8
Just everything needed to decode videos using UVD. v6: just all the bugfixes and support for R7xx-SI merged in one patch v7: UVD_CGC_GATE is a write only register, lockup detection fix v8: split out VRAM fallback changes, remove support for RV770, add support for HEMLOCK, add buffer sizes checks Signed-off-by: Christian König <christian.koenig@amd.com> Reviewed-by: Jerome Glisse <jglisse@redhat.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
