6.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Konrad Dybcio <konrad.dybcio@xxxxxxxxxx>
[ Upstream commit 2fd02de27054576a4a8c89302e2f77122c55e957 ]
All of the 8280's GCC GDSCs can and should use the retain registers so
as not to lose their state when entering lower power modes.
Fixes: d65d005f9a6c ("clk: qcom: add sc8280xp GCC driver")
