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