The TPD12S015 is an ESD clamp, level shifter and DC-DC converter, if it wasn't for the two control inputs CT_CP_HPD and LS_OE, we could probably do without a driver. I wouldn't add HPD support to this driver, as the chip really can't detect HPD. -- Regards, Laurent Pinchart _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
