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).
