Spreadtrum SC27xx Real Time Clock



Required properties:

- compatible: should be "sprd,sc2731-rtc".

- reg: address offset of rtc register.

- interrupt-parent: phandle for the interrupt controller.

- interrupts: rtc alarm interrupt.



Example:



	sc2731_pmic: pmic@0 {

		compatible = "sprd,sc2731";

		reg = <0>;

		spi-max-frequency = <26000000>;

		interrupts = <GIC_SPI 31 IRQ_TYPE_LEVEL_HIGH>;

		interrupt-controller;

		#interrupt-cells = <2>;

		#address-cells = <1>;

		#size-cells = <0>;



		rtc@280 {

			compatible = "sprd,sc2731-rtc";

			reg = <0x280>;

			interrupt-parent = <&sc2731_pmic>;

			interrupts = <2 IRQ_TYPE_LEVEL_HIGH>;

		};

	};
