From c29bc42790e83d41c51f50568590870f49711878 Mon Sep 17 00:00:00 2001 From: Vladimir Zapolskiy Date: Fri, 20 May 2022 00:41:33 +0300 Subject: [PATCH] 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.
