[PATCH v2 6/6] clk: qcom: gpucc-sa8775p: Update wait_val fields for GPU GDSC's

From: Taniya Das
Date: Wed Jun 12 2024 - 07:10:41 EST


Update wait_val fields as per the default hardware values of the GDSC as
otherwise it would lead to GDSC FSM state stuck causing power on/off
failures of the GSDC.

Fixes: 0afa16afc36d ("clk: qcom: add the GPUCC driver for sa8775p")
