+Dallas DS1307 and compatible RTC
+
+Required properties:
+- compatible: should be one of:
+ "dallas,ds1307",
+ "dallas,ds1308",
+ "dallas,ds1337",
+ "dallas,ds1338",
+ "dallas,ds1339",
+ "dallas,ds1388",
+ "dallas,ds1340",
+ "dallas,ds1341",

+ "microchip,mcp7940x",
+ "microchip,mcp7941x",
+ "pericom,pt7c4338",
+ "epson,rx8025",
+ "isil,isl12057"
+- reg: I2C bus address of the device
+
+Optional properties:
+- interrupt-parent: phandle for the interrupt controller.
+- interrupts: rtc alarm interrupt.
+- clock-output-names: From common clock binding to override the default output
+ clock name
+- wakeup-source: Enables wake up of host system on alarm
+
+Example:
+ rtc1: ds1339@68 {
+ compatible = "dallas,ds1339";
+ reg = <0x68>;
+ interrupt-parent = <&gpio4>;
+ interrupts = <20 0>;
+ };
