+* 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";
+       };
