[ Upstream commit 3f9a91b6c00e655d27bd785dcda1742dbdc31bda ]
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.
