Series [v3,1/6] clk: qcom: add two parent_map helpers | expand

Commit Message

Dmitry Baryshkov April 13, 2022, 11:31 p.m. UTC 
Use newly defined clk_regmap_mux_safe_ops for PCIe pipe clocks to let
the clock framework automatically park the clock when the clock is
switched off and restore the parent when the clock is switched on.
