* 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>;
};
