1* STMP3xxx/i.MX28 Time Clock controller
2
3Required properties:
4- compatible: should be one of the following.
5    * "fsl,stmp3xxx-rtc"
6- reg: physical base address of the controller and length of memory mapped
7  region.
8- interrupts: rtc alarm interrupt
9
10Optional properties:
11- stmp,crystal-freq: override crystal frequency as determined from fuse bits.
12  Only <32000> and <32768> are possible for the hardware.  Use <0> for
13  "no crystal".

17rtc@80056000 {
18	compatible = "fsl,imx28-rtc", "fsl,stmp3xxx-rtc";
19	reg = <0x80056000 2000>;
20	interrupts = <29>;
