+Texas Instruments DRA7x VIDEO PROCESSING ENGINE (VPE)
+------------------------------------------------------
+
+The Video Processing Engine (VPE) is a key component for image post
+processing applications. VPE consist of a single memory to memory
+path which can perform chroma up/down sampling, deinterlacing,
+scaling and color space conversion.
+
+Required properties:
+- compatible: must be "ti,vpe"
+- reg:	physical base address and length of the registers set for the 4
+	memory regions required;
+- reg-names: name associated with the memory regions described is <reg>;
+- interrupts: should contain IRQ line for VPE;
+
+Example:
+
+	target-module@1d0010 {                  /* 0x489d0000, ap 27 30.0 */
+		compatible = "ti,sysc-omap4", "ti,sysc";
+		reg = <0x1d0010 0x4>;
+		reg-names = "sysc";
+		ti,sysc-midle = <SYSC_IDLE_FORCE>,
+				<SYSC_IDLE_NO>,
+				<SYSC_IDLE_SMART>;
+		ti,sysc-sidle = <SYSC_IDLE_FORCE>,
+				<SYSC_IDLE_NO>,
+				<SYSC_IDLE_SMART>;
+		clocks = <&vpe_clkctrl DRA7_VPE_VPE_CLKCTRL 0>;
+		clock-names = "fck";
+		#address-cells = <1>;
+		#size-cells = <1>;
+		ranges = <0x0 0x1d0000 0x10000>;
+
+		vpe: vpe@0 {
+			compatible = "ti,vpe";
+			reg = <0x0000 0x120>,
+			      <0x0700 0x80>,
+			      <0x5700 0x18>,
+			      <0xd000 0x400>;
+			reg-names = "vpe_top",
+				    "sc",
+				    "csc",
+				    "vpdma";
+			interrupts = <GIC_SPI 354 IRQ_TYPE_LEVEL_HIGH>;
+			#address-cells = <1>;
+			#size-cells = <0>;
+		};
+	};
