It only gets used in HDMI/DVI modes, so EDP doesn't get one. Broadwell was able to properly rename transcoder stuff, so these became TRANS_MULT. _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
