6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Taniya Das <quic_tdas@xxxxxxxxxxx>
[ Upstream commit 211681998d706d1e0fff6b62f89efcdf29c24978 ]
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")
