>Subject: [PATCH 1/2] drm/radeon: enable display scaling on all connectors
>
>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.
