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",

	"maxim,ds3231",

	"st,m41t0",

	"st,m41t00",

	"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>;

	};
