    drm/radeon: enable display scaling on all connectors (v2) · da997620
    Alex Deucher 提交于
    This enables the display scaler on all connectors for r5xx
    and newer asics.  Previously we only enabled the scaler for
    fixed mode displays (eDP or LVDS) since they have to use the
    scaler to support non-native modes.  Most other displays
    are multi-sync or have a built in scaler to support non-native
    modes.  The default scaling mode for non-fixed displays is
    none which will use the scaler in the monitor.  Note that
    we do not populate any fake modes like we do for fixed
    displays so it will only use the modes in the edid.  For
    other modes, you'll need to populate them manually.
