This is a note to let you know that I've just added the patch titled clk: qcom: camcc-sm8250: Fix topology around titan_top power domain to the 5.18-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: clk-qcom-camcc-sm8250-fix-topology-around-titan_top-.patch and it can be found in the queue-5.18 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 1a7e1b6dbc1e6b058b1fbce40d0f48e1dee23062 Author: Vladimir Zapolskiy <vladimir.zapolskiy@xxxxxxxxxx> Date: Fri May 20 00:41:33 2022 +0300 clk: qcom: camcc-sm8250: Fix topology around titan_top power domain [ Upstream commit f8acf01a6a4f84baf05181e24bd48def4ba23f5b ] On SM8250 two found VFE GDSC power domains shall not be operated, if titan top is turned off, thus the former power domains will be set as subdomains by a GDSC registration routine.
