+* i.MX25 Real Time Clock controller
+
+This binding supports the following chips: i.MX25, i.MX53
+
+Required properties:
+- compatible: should be: "fsl,imx25-rtc"
+- reg: physical base address of the controller and length of memory mapped
+ region.
+- interrupts: rtc alarm interrupt
+
+Example:
+
+rtc@80056000 {
+ compatible = "fsl,imx53-rtc", "fsl,imx25-rtc";
+ reg = <0x80056000 2000>;
+ interrupts = <29>;
+};
