* Real Time Clock of the i.MX SoCs



RTC controller for the i.MX SoCs



Required properties:

- compatible: Should be "fsl,imx1-rtc" or "fsl,imx21-rtc".

- reg: physical base address of the controller and length of memory mapped

  region.

- interrupts: IRQ line for the RTC.

- clocks: should contain two entries:

  * one for the input reference

  * one for the the SoC RTC

- clock-names: should contain:

  * "ref" for the input reference clock

  * "ipg" for the SoC RTC clock



Example:



rtc@10007000 {

	compatible = "fsl,imx21-rtc";

	reg = <0x10007000 0x1000>;

	interrupts = <22>;

	clocks = <&clks IMX27_CLK_CKIL>,

		 <&clks IMX27_CLK_RTC_IPG_GATE>;

	clock-names = "ref", "ipg";

};
