v3:
- Rename compatible string to "img,ir-rev1" (Rob Herring).
- Specify ordering of clocks explicitly (Rob Herring).
v2:
- Future proof compatible string from "img,ir" to "img,ir1", where the 1
corresponds to the major revision number of the hardware (Tomasz
Figa).
- Added clock-names property and three specific clock names described in
the manual, only one of which is used by the current driver (Tomasz
Figa).

+* ImgTec Infrared (IR) decoder version 1
+
+This binding is for Imagination Technologies' Infrared decoder block,
+specifically major revision 1.
+
+Required properties:
+- compatible: Should be "img,ir-rev1"
+- reg: Physical base address of the controller and length of
+ memory mapped region.
+- interrupts: The interrupt specifier to the cpu.
+
+Optional properties:
+- clocks: List of clock specifiers as described in standard
+ clock bindings.
+ Up to 3 clocks may be specified in the following order:
+ 1st: Core clock (defaults to 32.768KHz if omitted).
+ 2nd: System side (fast) clock.
+ 3rd: Power modulation clock.
+- clock-names: List of clock names corresponding to the clocks
+ specified in the clocks property.
+ Accepted clock names are:
+ "core": Core clock.
+ "sys": System clock.
+ "mod": Power modulation clock.
+
+Example:
+
+ ir@02006200 {
+ compatible = "img,ir-rev1";
+ reg = <0x02006200 0x100>;
+ interrupts = <29 4>;
+ clocks = <&clk_32khz>;
+ clock-names = "core";
+ };
