* 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@80056000 {
compatible = "fsl,imx28-rtc", "fsl,stmp3xxx-rtc";
reg = <0x80056000 2000>;
interrupts = <29>;
};
