[PATCH 3/3] drm/radeon: add audio support for DCE6/8 GPUs (v9)
Alex Deucher
alexdeucher at gmail.com
Wed Aug 14 09:08:15 PDT 2013
Similar to DCE4/5, but supports multiple audio pins
which can be assigned per afmt block.
v2: rework the driver to handle more than one audio
pin.
v3: try different dto reg
v4: properly program dto
v5 (ck): change dto programming order
v6: program speaker allocation block
v7: rebase
v8: rebase on Rafał's changes
v9: integrated Rafał's comments, update to latest
drm_edid_to_speaker_allocation API
