[PATCHv3 2/3] devicetree: Add new ANX7814 SlimPort transmitter binding.

[Enric Balletbo i Serra]

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

You can add support to your board with current binding.

Example:

anx7814: anx7814@38 {
compatible = "analogix,anx7814";
reg = <0x38>;
pd-gpios = < 1 GPIO_ACTIVE_HIGH>;
reset-gpios = < 2 GPIO_ACTIVE_HIGH>;
};

I saw after sending the series that there was some discussion here,
let me paste to not forget it.

But what if the chip is connected to a display controller, for instance to the
HDMI output of an SoC ? Is that a use case for the hardware ?
