This converts the Analogix ANX7814 bridge DT binding to yaml. Port definitions and descriptions were expanded, apart from that it's a direct translation from the original binding.

-Analogix ANX7814 SlimPort (Full-HD Transmitter)

-The ANX7814 is an ultra-low power Full-HD (1080p60) SlimPort transmitter -designed for portable devices.

-Required properties:

• • compatible : Must be one of:

• 	  "analogix,anx7808"
  

• 	  "analogix,anx7812"
  

• 	  "analogix,anx7814"
  

• 	  "analogix,anx7818"
  

• • reg : I2C address of the device
• • interrupts : Should contain the INTP interrupt
• • hpd-gpios : Which GPIO to use for hpd
• • pd-gpios : Which GPIO to use for power down
• • reset-gpios : Which GPIO to use for reset

-Optional properties:

• • dvdd10-supply : Regulator for 1.0V digital core power.
• • Video port for HDMI input, using the DT bindings defined in [1].

-Example:

• anx7814: anx7814@38 {

• compatible = "analogix,anx7814";
  

• reg = <0x38>;
  

• interrupt-parent = <&gpio0>;

Can drop the description as there's nothing specific to this device.

I don't' think you need to specify this. You can drop it (better double check with Rob, though)

This should be "bridge@38 {", since node names are supposed to match the class of the device instead of the name of the device. I guess.
