Is it still the planned implementation?

Here is how the dts rpmhcc node will look like: rpmhcc: clock-controller { compatible = "qcom,sm8550-rpmh-clk"; #clock-cells = <1>; clock-names = "xo"; clocks = <&xo_board>; bi_tcxo_div2: bi-tcxo-div2-clk { #clock-cells = <0>; compatible = "fixed-factor-clock"; clocks = <&rpmhcc RPMH_CXO_CLK>; clock-mult = <1>; clock-div = <2>; }; bi_tcxo_ao_div2: bi-tcxo-div2-ao-clk { #clock-cells = <0>; compatible = "fixed-factor-clock"; clocks = <&rpmhcc RPMH_CXO_CLK_A>; clock-mult = <1>; clock-div = <2>; }; }; The clock nodes will be probed on of_clk_init. > > -- > With best wishes > Dmitry >

Ah, I see. of_clk_init() will initialize clocks even if the parent device is not fully probed. Thank you for the explanation!
