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>;
};
};
