* APM X-Gene Real Time Clock RTC controller for the APM X-Gene Real Time Clock Required properties: - compatible : Should be "apm,xgene-rtc" - reg: physical base address of the controller and length of memory mapped region. - interrupts: IRQ line for the RTC. - #clock-cells: Should be 1. - clocks: Reference to the clock entry. Example: rtcclk: rtcclk { compatible = "fixed-clock"; #clock-cells = <1>; clock-frequency = <100000000>; clock-output-names = "rtcclk"; }; rtc: rtc@10510000 { compatible = "apm,xgene-rtc"; reg = <0x0 0x10510000 0x0 0x400>; interrupts = <0x0 0x46 0x4>; #clock-cells = <1>; clocks = <&rtcclk 0>; };
