Subject: [PATCH 0/3] clk: qcom: gdsc: add support for collapse-vote registers

Recent Qualcomm platforms have APCS collapse-vote registers that allow
for sharing GDSCs with other masters (e.g. LPASS).
    
Add support for using such vote registers instead of the control
register when updating the GDSC power state.

Note that the gcc-sc8280xp driver has not yet been merged. [1]
