Description
|
|
-----------
|
|
|
|
This driver implements support for hardware monitoring commands exposed by the
|
|
ChromeOS embedded controller used in Chromebooks and other devices.
|
|
|
|
The channel labels exposed via hwmon are retrieved from the EC itself.
|
|
|
|
Fan and temperature readings are supported.
