+description: |
+ ChromeOS EC ANX7688 is a display bridge that converts HDMI 2.0 to
+ DisplayPort 1.3 Ultra-HDi (4096x2160p60). It is an Analogix ANX7688 chip
+ which is connected to and operated by the ChromeOS Embedded Controller
+ (See google,cros-ec.yaml). It is accessed using I2C tunneling through
+ the EC and therefore its node should be a child of an EC I2C tunnel node
+ (See google,cros-ec-i2c-tunnel.yaml).

-* Faraday TV Encoder TVE200
-
-Required properties:
-
-- compatible: must be one of:
- "faraday,tve200"
- "cortina,gemini-tvc", "faraday,tve200"
-
-- reg: base address and size of the control registers block
-
-- interrupts: contains an interrupt specifier for the interrupt
- line from the TVE200
-
-- clock-names: should contain "PCLK" for the clock line clocking the
- silicon and "TVE" for the 27MHz clock to the video driver
-
-- clocks: contains phandle and clock specifier pairs for the entries
- in the clock-names property. See
- Documentation/devicetree/bindings/clock/clock-bindings.txt
-
-Optional properties:
-
-- resets: contains the reset line phandle for the block
-
-Required sub-nodes:
-
-- port: describes LCD panel signals, following the common binding
- for video transmitter interfaces; see
- Documentation/devicetree/bindings/media/video-interfaces.txt
- This port should have the properties:
- reg = <0>;
- It should have one endpoint connected to a remote endpoint where
- the display is connected.
-
-Example:
-
-display-controller@6a000000 {
- #address-cells = <1>;
- #size-cells = <0>;
- compatible = "faraday,tve200";
- reg = <0x6a000000 0x1000>;
- interrupts = <13 IRQ_TYPE_EDGE_RISING>;
- resets = <&syscon GEMINI_RESET_TVC>;
- clocks = <&syscon GEMINI_CLK_GATE_TVC>,
- <&syscon GEMINI_CLK_TVC>;
- clock-names = "PCLK", "TVE";
-
- port@0 {
- reg = <0>;
- display_out: endpoint {
- remote-endpoint = <&panel_in>;
- };
- };
-};
