I've ping'd Stephen privately on IRC multiple times, and it's basically a resend of the previous clock series linked above that has been around since almost a month and a half. Can you Ack the first three patches so we can merge those patches through the DRM tree and close this regression? Maxime
Hi, Those patches used to be part of a larger clock fixes series: https://lore.kernel.org/linux-clk/20220715160014.2623107-1-maxime@cerno.tech/ However, that series doesn't seem to be getting anywhere, so I've split out these patches that fix a regression that has been there since 5.18 and that prevents the 4k output from working on the RaspberryPi4. Hopefully, we will be able to merge those patches through the DRM tree to avoid any further disruption.
