-* 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";
-};
