If anyone has any objections, please let me know. ------------------ From: Sushaanth Srirangapathi commit 713fced8d10fa1c759c8fb6bf9aaa681bae68cad upstream. Commit 028cd86b794f4a ("video: da8xx-fb: fix the polarities of the hsync/vsync pulse") fixes polarities of HSYNC/VSYNC pulse but forgot to update known_lcd_panels[] which had sync values according to old logic. This breaks LCD at least on DA850 EVM. This patch fixes this issue and I have tested this for panel "Sharp_LK043T1DG01" using DA850 EVM board.
