Required properties:
- compatible : "st,spear600-rtc"
- reg : Address range of the rtc registers
- interrupt-parent: Should be the phandle for the interrupt controller
that services interrupts for this device
- interrupt: Should contain the rtc interrupt number
Example:
rtc@fc000000 {
compatible = "st,spear600-rtc";
reg = <0xfc000000 0x1000>;
interrupt-parent = <&vic1>;
interrupts = <12>;
};
