From 70dc5425fe1af90901d8109941e09005de38b7ea Mon Sep 17 00:00:00 2001 From: Vladimir Zapolskiy Date: Wed, 22 Oct 2025 02:44:50 +0300 Subject: [PATCH] clk: qcom: camcc-sm8450: Specify Titan GDSC power domain as a parent to IPE/BPS/SBI 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 described in the CAMCC driver. Establish the power domain hierarchy with a Titan GDSC set as a parent of other GDSC power domains provided by the SM8450 camera clock controller, including IPE, BPS and SBI ones.
