+OMAP Dynamic Memory Manager (DMM) bindings
+
+Required properties:
+- compatible: Must be "ti,omap4-dmm" for OMAP4 family
+ Must be "ti,omap5-dmm" for OMAP5 and DRA7x family
+- 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 DMM, which is typically "dmm"
+
+Example:
+
+dmm@4e000000 {
+ compatible = "ti,omap4-dmm";
+ reg = <0x4e000000 0x800>;
+ ti,hwmods = "dmm";
