+The THC63LVD1024 is a dual link LVDS receiver designed to convert LVDS streams +to parallel data outputs. The chip supports single/dual input/output modes, +handling up to two two input LVDS stream and up to two digital CMOS/TTL outputs.

+Required properties: +- compatible: Shall be "thine,thc63lvd1024",

+Optional properties: +- vcc-supply: Power supply for TTL output and digital circuitry +- cvcc-supply: Power supply for TTL CLOCKOUT signal +- lvcc-supply: Power supply for LVDS inputs +- pvcc-supply: Power supply for PLL circuitry +- pdwn-gpios: Power down GPIO signal. Active low. +- oe-gpios: Output enable GPIO signal. Active high.

Nitpick: different lines ends differently: period, dot, nothing. Another thing if there will be next iteration it would be good to emphasize converter has no control bus. Anyway:

+The THC63LVD1024 video port connections are modeled according +to OF graph bindings specified by Documentation/devicetree/bindings/graph.txt

+Required video port nodes: +- Port@0: First LVDS input port +- Port@2: First digital CMOS/TTL parallel output

+Optional video port nodes: +- Port@1: Second LVDS input port +- Port@3: Second digital CMOS/TTL parallel output
