+* Real Time Clock of the Armada 38x SoCs
+
+RTC controller for the Armada 38x SoCs
+
+Required properties:
+- compatible : Should be "marvell,armada-380-rtc"
+- reg: a list of base address and size pairs, one for each entry in
+ reg-names
+- reg names: should contain:
+ * "rtc" for the RTC registers
+ * "rtc-soc" for the SoC related registers and among them the one
+ related to the interrupt.
+- interrupts: IRQ line for the RTC.
+
+Example:
+
+rtc@a3800 {
+ compatible = "marvell,armada-380-rtc";
+ reg = <0xa3800 0x20>, <0x184a0 0x0c>;
+ reg-names = "rtc", "rtc-soc";
+ interrupts = <GIC_SPI 21 IRQ_TYPE_LEVEL_HIGH>;
+};
