* i.MX25 Real Time Clock controller
|
||||
|
||||
This binding supports the following chips: i.MX25, i.MX53
|
||||
|
||||
Required properties:
|
||||
- compatible: should be: "fsl,imx25-rtc"
|
||||
- reg: physical base address of the controller and length of memory mapped
|
||||
region.
|
||||
- interrupts: rtc alarm interrupt
|
||||
|
||||
Example:
|
||||
|
||||
rtc@80056000 {
|
||||
compatible = "fsl,imx53-rtc", "fsl,imx25-rtc";
|
||||
reg = <0x80056000 2000>;
|
||||
interrupts = <29>;
|
||||
};
