Uh, I spoke to early, my bad. I made a mistake when I calculated rate deviation for 768p last time - I took 73MHz as dotclock, but actual requested rate 72.3 MHz and it gets 72.296296 MHz, so it's within 0.5% tolerance. 1080p pinebook needs 138.5 MHz and gets 138.461538 MHz - also within 0.5%. However your patch has an issue, I'll respond to your previous email. > Maxime > > -- > Maxime Ripard, Bootlin > Embedded Linux and Kernel engineering > https://bootlin.com
