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).
