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