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