+OMAP Counter-32K bindings
+
+Required properties:
+- compatible:  Must be "ti,omap-counter32k" for OMAP controllers
+- reg:         Contains timer register address range (base address and length)
+- ti,hwmods:   Name of the hwmod associated to the counter, which is typically
+               "counter_32k"
+
+Example:
+
+counter32k: counter@4a304000 {
+       compatible = "ti,omap-counter32k";
+       reg = <0x4a304000 0x20>;
+       ti,hwmods = "counter_32k";
+};
