Thine Electronics THC63LVD1024 LVDS decoder
-------------------------------------------
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 LVDS input streams and up to two digital CMOS/TTL outputs.
Single or dual operation mode, output data mapping and DDR output modes are
configured through input signals and the chip does not expose any control bus.
Required properties:
- compatible: Shall be "thine,thc63lvd1024"
- vcc-supply: Power supply for TTL output, TTL CLOCKOUT signal, LVDS input,
PPL and digital circuitry
Optional properties:
- powerdown-gpios: Power down GPIO signal, pin name "/PDWN". Active low
- oe-gpios: Output enable GPIO signal, pin name "OE". Active high
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
Example:
--------
thc63lvd1024: lvds-decoder {
compatible = "thine,thc63lvd1024";
vcc-supply = <&reg_lvds_vcc>;
powerdown-gpios = <&gpio4 15 GPIO_ACTIVE_LOW>;
ports {
#address-cells = <1>;
#size-cells = <0>;
port@0 {
reg = <0>;
lvds_dec_in_0: endpoint {
remote-endpoint = <&lvds_out>;
};
};
port@2{
reg = <2>;
lvds_dec_out_2: endpoint {
remote-endpoint = <&adv7511_in>;
};
};
};
};
