[PATCH 6.10 416/809] clk: qcom: gpucc-sa8775p: Update wait_val fields for GPU GDSCs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.10-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.
