+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";
+};
