TFP410 DPI to DVI encoder
=========================
Required properties:
- compatible: "ti,tfp410"
Optional properties:
- powerdown-gpios: power-down gpio
- reg: I2C address. If and only if present the device node should be placed
into the I2C controller node where the TFP410 I2C is connected to.
- ti,deskew: data de-skew in 350ps increments, from -4 to +3, as configured
through th DK[3:1] pins. This property shall be present only if the TFP410
is not connected through I2C.
Required nodes:
This device has two video ports. Their connections are modeled using the OF
graph bindings specified in [1]. Each port node shall have a single endpoint.
- Port 0 is the DPI input port. Its endpoint subnode shall contain a
pclk-sample and bus-width property and a remote-endpoint property as specified
in [1].
- If pclk-sample is not defined, pclk-sample = 0 should be assumed for
backward compatibility.
- If bus-width is not defined then bus-width = 24 should be assumed for
backward compatibility.
bus-width = 24: 24 data lines are connected and single-edge mode
bus-width = 12: 12 data lines are connected and dual-edge mode
- Port 1 is the DVI output port. Its endpoint subnode shall contain a
remote-endpoint property is specified in [1].
