   13   ChromeOS EC ANX7688 is a display bridge that converts HDMI 2.0 to
   14   DisplayPort 1.3 Ultra-HDi (4096x2160p60). It is an Analogix ANX7688 chip
   15   which is connected to and operated by the ChromeOS Embedded Controller
   16   (See google,cros-ec.yaml). It is accessed using I2C tunneling through
   17   the EC and therefore its node should be a child of an EC I2C tunnel node
   18   (See google,cros-ec-i2c-tunnel.yaml).
