| description: | |
| 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). |
