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