* 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";
|
|
};
