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 = <&gpio0 1 GPIO_ACTIVE_HIGH>;
reset-gpios = <&gpio0 2 GPIO_ACTIVE_HIGH>;
};

No ports needed for describing data connections?

IMHO I'm not sure if this is applicable here, in this case the bridge
is transparent so it's not required another device node. For example,
I've an evaluation board, whre I connect in one side an HDMI input
signal an in the other side a DP monitor, the driver only configures
the chip and waits for different events (cable plug, cable unplug, etc
..)
Cheers,
Enric

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 ?
