From d988b0b866c2aeb23aa74022b5bbd463165a7a33 Mon Sep 17 00:00:00 2001 From: Luca Weiss Date: Fri, 25 Apr 2025 14:12:58 +0200 Subject: [PATCH] clk: qcom: gpucc-sm6350: Add *_wait_val values for GDSCs Compared to the msm-4.19 driver the mainline GDSC driver always sets the bits for en_rest, en_few & clk_dis, and if those values are not set per-GDSC in the respective driver then the default value from the GDSC driver is used. The downstream driver only conditionally sets clk_dis_wait_val if qcom,clk-dis-wait-val is given in devicetree. Correct this situation by explicitly setting those values. For all GDSCs the reset value of those bits are used, with the exception of gpu_cx_gdsc which has an explicit value (qcom,clk-dis-wait-val = <8>).
