* 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";
};
