From: Fabio Estevam <fabio.estevam@xxxxxxx>
Improve the bindings text by doing the following changes:
- Remove the i.MX53 reference, as the RTC on i.MX53 is a different hardware
- Add 'clocks' to the list of required properties
- Explain that the optional security violation irq is the second entry
- Use the real unit address and irq numbers for i.MX25

* 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.
+- clocks: should contain the phandle for the rtc clock
- interrupts: rtc alarm interrupt
Optional properties:
-- interrupts: dryice security violation interrupt
+- interrupts: dryice security violation interrupt (second entry)
Example:
-rtc@80056000 {
- compatible = "fsl,imx53-rtc", "fsl,imx25-rtc";
- reg = <0x80056000 2000>;
- interrupts = <29 56>;
+rtc@53ffc000 {
+ compatible = "fsl,imx25-rtc";
+ reg = <0x53ffc000 0x4000>;
+ clocks = <&clks 81>;
+ interrupts = <25 56>;
};
