    drm/radeon: rework panel mode setup · 0ceb996c
    Alex Deucher authored
    Adjust the panel mode setup to match the behavior
    of the vbios.  Rather than checking for specific
    bridge chip ids, just check the eDP configuration register.
    This saves extra aux transactions and works across
    DP bridge chips without requiring additional per chip
    id checking.
