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.

+description: |
+ ANX7688 converts HDMI 2.0 to DisplayPort 1.3 Ultra-HDi (4096x2160p60)
+ including an intelligent crosspoint switch to support USB Type-C (USB-C).
+ The integrated crosspoint switch supports USB 3.1 data transfer along with
+ the DisplayPort Alternate Mode signaling over USB Type-C. Additionally,
+ an on-chip microcontroller (OCM) is available to manage the signal switching,
+ Channel Configuration (CC) detection, USB Power Delivery (USB-PD), Vendor
+ Defined Message (VDM) protocol support and other functions as defined in the
+ USB TypeC and USB Power Delivery specifications.
+
+ As a result, a multi-function device is exposed as parent of the video
+ bridge, TCPC and MUX blocks.
