+ On ChromeOS systems with USB Type C ports, the ChromeOS Embedded Controller is
+ able to detect the state of external accessories such as display adapters
+ or USB devices when said accessories are attached or detached.
+ The node for this device must be under a cros-ec node like google,cros-ec-spi
+ or google,cros-ec-i2c.
