The Innolux G101ICE-L01 datasheet [1] page 17 table 6.1 INPUT SIGNAL TIMING SPECIFICATIONS indicates that maximum vertical blanking time is 40 lines. Currently the driver uses 29 lines. Fix it, and since this panel is a DE panel, adjust the timings to make them less hostile to controllers which cannot do 1 px HSA/VSA, distribute the delays evenly between all three parts.
