Texas Instruments FPD-Link (LVDS) Serializer
--------------------------------------------
The DS90C185 and DS90C187 are low-power serializers for portable
battery-powered applications that reduces the size of the RGB
interface between the host GPU and the display.
Required properties:
- compatible: Should be
"ti,ds90c185", "lvds-encoder" for the TI DS90C185 FPD-Link Serializer
"ti,ds90c187", "lvds-encoder" for the TI DS90C187 FPD-Link Serializer
Optional properties:
- powerdown-gpios: Power down control GPIO (the PDB pin, active-low)
Required nodes:
The devices have two video ports. Their connections are modeled using the OF
graph bindings specified in Documentation/devicetree/bindings/graph.txt.
- Video port 0 for parallel input
- Video port 1 for LVDS output
Example
-------
lvds-encoder {
compatible = "ti,ds90c185", "lvds-encoder";
powerdown-gpios = <&gpio 17 GPIO_ACTIVE_LOW>;
ports {
#address-cells = <1>;
