Add devicetree probing, fixing some whitespace damage along the way.
Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
---
changes since v1:
- document 'intrerrupts' property as mandatory, because the driver needs it.

+* i.MX25 dryice Real Time Clock controller

+This RTC is part of the i.MX25 dryice module. Documentation for this
+unit is not publically available. This binding only makes use of the
+RTC.
+
+Required properties:
+- compatible: should be "fsl,imx25-rtc"
+- reg: physical base address of the controller and length of memory mapped
+ region.
+- interrupts: interrupt source for the dryice module

+Example:
+
+ dryice at 53ffc000 {
+ compatible = "fsl,imx25-dryice", "fsl,imx25-rtc";
+ reg = <0x53ffc000 0x4000>;
+ interrupts = <25>;

Alessandro,
Everything fine with this patch? If yes, could you apply it?
Thanks
