| Message-ID | <rslGj-kK-39@gated-at.bofh.it> |
3.16.35-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Sushaanth Srirangapathi <sushaanth.s@ti.com>
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")
