    Subject[PATCH 3.12 16/76] fbdev: da8xx-fb: fix videomodes of lcd panels
    Date
    From: Sushaanth Srirangapathi <sushaanth.s@ti.com>

    3.12-stable review patch. If anyone has any objections, please let me know.

    ===============

    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.

    Fixes: 028cd86b794f4a ("video: da8xx-fb: fix the polarities of the hsync/vsync pulse")
