Ok, I've done more detailed testing, and it seems this patch results in lots of dropped frames. I'm sorry for not being more thorough earlier. I'll do some more testing without this patch and might have to either remove it from V2 of this series. I need to see if the same stability can be achiev

[PATCH 5/5] drm/panel: st7703: Drive XBD599 panel at higher clock rate

2023-12-18 Thread Frank Oltmanns
This panel is used in the pinephone that runs on a Allwinner A64 SOC. Acoording to it's datasheet, the SOC requires PLL-MIPI to run at more than 500 MHz. Therefore, change [hv]sync_(start|end) so that we reach a clock rate that is high enough to drive PLL-MIPI within its limits. Signed-off-by: Fr
