-+Kernel driver rpi-poe-fan
-+=====================
-+
-+This driver enables the use of the Raspberry Pi PoE HAT fan.
-+
-+Author: Serge Schneider <serge@raspberrypi.org>
-+
-+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.
