Description
|
|
-----------
|
|
|
|
The driver implements a simple interface for driving the Raspberry Pi PoE
|
|
(Power over Ethernet) HAT fan. The driver passes commands to the Raspberry Pi
|
|
firmware through the mailbox property interface. The firmware then forwards
|
|
the commands to the board over I2C on the ID_EEPROM pins. The driver exposes
|
|
the fan to the user space through the hwmon sysfs interface.
