Subject: [PATCH v2 0/7] drm/vc4: Fix the core clock behaviour
Date: Tue, 20 Sep 2022 14:50:19 +0200 [thread overview]
Message-ID: <20220815-rpi-fix-4k-60-v2-0-983276b83f62@cerno.tech> (raw)
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.
Let me know what you think,
Maxime
