From ee2867ca99e2b5b6788ff421f7e784d9a0da426f Mon Sep 17 00:00:00 2001 From: Vladimir Zapolskiy Date: Wed, 22 Oct 2025 02:44:47 +0300 Subject: [PATCH] clk: qcom: camcc-sdm845: Specify Titan GDSC power domain as a parent to other When a consumer turns on/off a power domain dependent on another power domain in hardware, the parent power domain shall be turned on/off by the power domain provider as well, and to get it the power domain hardware hierarchy shall be properly described in the power domain provider driver. Establish the power domain hierarchy with a Titan GDSC set as a parent of other GDSC power domains provided by the SDM845 camera clock controller, including IPE0/1 and BPS ones.
