dt-bindings: display: bridge: fork out ti, ds90c185 from lvds-transmitter

Required properties:

- compatible: Must be one or more of the following

  - "ti,ds90c185" for the TI DS90C185 FPD-Link Serializer

  - "lvds-encoder" for a generic LVDS encoder device

- compatible: Must be "lvds-encoder"

  When compatible with the generic version, nodes must list the

  device-specific version corresponding to the device first

  followed by the generic version.

  Any encoder compatible with this generic binding, but with additional

  properties not listed here, must list a device specific compatible first

  followed by this generic compatible.

Required nodes:

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>;

		#size-cells = <0>;

		port@0 {

			reg = <0>;

			lvds_enc_in: endpoint {

				remote-endpoint = <&lcdc_out_rgb>;

			};

		};

		port@1 {

			reg = <1>;

			lvds_enc_out: endpoint {

				remote-endpoint = <&lvds_panel_in>;

			};

		};

	};

};
