+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: counter32k@4a304000 {
+ compatible = "ti,omap-counter32k";
+ reg = <0x4a304000 0x001f>;
