+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>;
+ };
+ };
