| Subject: fbdev: da8xx-fb: fix videomodes of lcd panels |
| |
| 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") |
