* i.MX53 Secure Real Time Clock (SRTC)
Required properties:
- compatible: should be: "fsl,imx53-rtc"
- reg: physical base address of the controller and length of memory mapped
region.
- clocks: should contain the phandle for the rtc clock
- interrupts: rtc alarm interrupt
Example:
rtc@53fa4000 {
compatible = "fsl,imx53-rtc";
reg = <0x53fa4000 0x4000>;
interrupts = <24>;
clocks = <&clks IMX5_CLK_SRTC_GATE>;
};
