Yes. 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.
