Subject: [PATCH 5.4 121/183] clk: qcom: dispcc-sdm845: Adjust internal GDSC wait times
From: Konrad Dybcio <konrad.dybcio@...aro.org>
[ Upstream commit 117e7dc697c2739d754db8fe0c1e2d4f1f5d5f82 ]
SDM845 downstream uses non-default values for GDSC internal waits.
Program them accordingly to avoid surprises.
Fixes: 81351776c9fb ("clk: qcom: Add display clock controller driver for SDM845")
