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.

Considering that the remainder of the clock exposed (except ipa clock)
by the rpmhcc provider represent clock signals coming out of the pmic;
and that this divider is not located in the aoss (rsc), I don't think
these nodes should live here.
/clocks seems perfectly fine to me.

Does this snippet pass bindings validation?

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