-* STMP3xxx/i.MX28 Time Clock controller
-
-Required properties:
-- compatible: should be one of the following.
- * "fsl,stmp3xxx-rtc"
-- reg: physical base address of the controller and length of memory mapped
- region.
-- interrupts: rtc alarm interrupt
-
-Optional properties:
-- stmp,crystal-freq: override crystal frequency as determined from fuse bits.
- Only <32000> and <32768> are possible for the hardware. Use <0> for
- "no crystal".

-Example:
-
-rtc@...56000 {
- compatible = "fsl,imx28-rtc", "fsl,stmp3xxx-rtc";
- reg = <0x80056000 2000>;
- interrupts = <29>;
