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.
Tony
