Texas Instruments DRA7x VIDEO INPUT PORT (VIP)
----------------------------------------------

The Video Input Port (VIP) is a key component for image capture
applications. The capture module provides the system interface and the
processing capability to connect parallel image-sensor as well as
BT.656/1120 capable encoder chip.

Required properties:
- compatible: must be "ti,vip1", "ti,vip2" or "ti,vip3".
- reg:	VIP top level, parser, colorspace converter, scaler for slice 0 and 1
	and vpdma memory address space;
- reg-names: vip, parser0, csc0, sc0, parser1, csc1, sc1 and vpdma registers;
- interrupts: should contain IRQ line for VIP;
- syscon-pol: phandle to the device control module;

VIP supports 2 slices. Each slice can handle up to 2 camera port nodes.
Each port nodes should contain a 'port' child node with child 'endpoint'
node. Please refer to the bindings defined in
Documentation/devicetree/bindings/media/video-interfaces.txt.

Example:
	vip1: vip@0x48970000 {
		compatible = "ti,vip1";
		reg = <0x48970000 0x114>,

	};
