I come with below RFC patch. if no objection I'll move forward with it.

Thanks for following through with this!

The am335x will also need the MUX in its clock tree, won't it?

Not exactly. I do not see CPTS_RFTCLK_SEL register in trm, but looks like
it's already implemented in am335 clock tree:
	cpsw_cpts_rft_clk: cpsw_cpts_rft_clk@520 {
		#clock-cells = <0>;
		compatible = "ti,mux-clock";
		clocks = <&dpll_core_m5_ck>, <&dpll_core_m4_ck>;
		reg = <0x0520>;
	};

and ssigned-clock-xx can be used to change parent in board file:

&cpsw_cpts_rft_clk {
assigned-clocks = <&cpsw_cpts_rft_clk>;
assigned-clock-parents = <&dpll_core_m4_ck>;
};
