The ANX7688 chip is a Type-C Port Controller, HDMI to DP converter and USB-C mux between USB 3.0 lanes and the DP output. For our use case a big part of the chip, like power supplies, control gpios and the usb-c part is managed by an Embedded Controller, hence, this is its simplest form of the binding. We'd prefer introduce these properties for someone with a different use case so they can test on their hardware.
