Is this a "linux" property? It seems like something that other OSes would want to know about and doesn't require any explicit knowledge about operating system things (like keymaps for example).

+
+ rtc {rtc@11d
+ compatible = "qcom,pm8921-rtc"; + reg = <0x11D>; + reg-names = "rtc_base"; + interrupts = <0x27 0>; + interrupt-names = "alarm"; + };
