+OMAP Dynamic Memory Manager (DMM) bindings
+
+Required properties:
+- compatible: Must be "ti,dmm" for OMAP processors containing DMM block
+- reg: Contains timer register address range (base address and length)
+- interrupts: Contains interrupt information (source, etc) for the DMM IRQ
+- ti,hwmods: Name of the hwmod associated to the counter, which is typically
+ "dmm"
+
+Example:
+
+dmm: dmm@4e000000 {
+ compatible = "ti,dmm";
+ reg = <0x4e000000 0x800>;
+ ti,hwmods = "dmm";
+};
