Pls, correct me if I'm not right. Is below what you propose?

Doard dts:
/ {
  rtc_32k_ext_clk: rtc_osc_xi_clkin32_ext {
	#clock-cells = <0>;
	compatible = "fixed-clock";
	clock-frequency = <32000>;
   	clock-output-names = "rtc_osc_xi_clkin32";
   };
}

  &rtc {
  	status = "okay";
	clocks = <&sys_32k_ck>, <&rtc_32k_ext_clk>;
	[optional] clock-names = "int-clk", "ext-clk";
  };

Driver:
1) clk0 is mandatory, internal clock source
2) clk1 is optional, external clock source, so
if present - RTC driver can switch to use ext clock source

Thanks Grygorii. I will implement it this way.

Absolutely!

Sounds good to me too.
