-* i.MX25 Real Time Clock controller
-
-Required properties:
-- compatible: should be: "fsl,imx25-rtc"
-- reg: physical base address of the controller and length of memory mapped
-  region.
-- clocks: should contain the phandle for the rtc clock
-- interrupts: rtc alarm interrupt
-
-Optional properties:
-- interrupts: dryice security violation interrupt (second entry)
-
-Example:
-
-rtc@53ffc000 {
-       compatible = "fsl,imx25-rtc";
-       reg = <0x53ffc000 0x4000>;
-       clocks = <&clks 81>;
-       interrupts = <25 56>;
