+* Real Time Clock for Renesas SH and ARM SoCs
+
+Required properties:
+- compatible: Should be "renesas,r7s72100-rtc" or "renesas,sh-rtc" as a
+ fallback.
+- reg: physical base address and length of memory mapped region.
+- interrupts: 3 interrupts for alarm, period, and carry.
+- clocks: the clock source for the RTC controller.
+
+Example:
+rtc: rtc@fcff1000 {
+ compatible = "renesas,r7s72100-rtc", "renesas,sh-rtc";
+ reg = <0xfcff1000 0x2e>;
+ interrupts = <GIC_SPI 276 IRQ_TYPE_EDGE_RISING
+ GIC_SPI 277 IRQ_TYPE_EDGE_RISING
+ GIC_SPI 278 IRQ_TYPE_EDGE_RISING>;
+ clocks = <&mstp6_clks R7S72100_CLK_RTC>;
+ power-domains = <&cpg_clocks>;
+};
