    drm/radeon/atom: powergating fixes for DCE6 · c205b232
    Alex Deucher authored
    Power gating is per crtc pair, but the powergating registers
    should be called individually.  The hw handles power up/down
    properly.  The pair is powered up if either crtc in the pair
    is powered up and the pair is not powered down until both
    crtcs in the pair are powered down.  This simplifies
    programming and should save additional power as the previous
    code never actually power gated the crtc pair.
