7 title: ChromeOS EC ANX7688 HDMI to DP Converter through Type-C Port
10 - Nicolas Boichat <drinkcat@chromium.org>
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
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
