    drm/i915: add color key support v4 · 8ea30864
    Jesse Barnes authored
    Add new ioctls for getting and setting the current destination color
    key.  This allows for simple overlay display control by matching a color
    key value in the primary plane before blending the overlay on top.
    
    v2: remove unnecessary mutex acquire/release around reg accesses
    v3: add support for full color key management
    v4: fix copy & paste bug in snb_get_colorkey
        don't bother checking min/max values against docs as the docs are likely
        wrong (how could we handle 10bpc surface formats?)
