Where did you get the timings from then?
You mean drm_mode timings, the same panel with RGB available in panel-simple[1], and dsi driver in Mailing list[2] and actual DSI sequence commands from BSP[3]
[1] https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/d... [2] https://patchwork.kernel.org/patch/10680331/ [3] https://github.com/BPI-SINOVOIP/BPI-M64-bsp/blob/master/linux-sunxi/drivers/...
So you had no reliable source for the timings then? How do you know if all your patches that are timing related are right then?
I don't understand your point, or may be I confused with many links that I attached in previous mail.
- Patch for same panel timings are already in Mainline that was
tested on one of the board. [1] 2. Driver from AW, released bsp from BPI-M64-bsp [3]
Do you think the above two points are not valid sources?
fyi, the panel datasheet attached in above mail has timing information.
Do you have a page number?
