Kernel driver pwm-fan
|
||
|
|
=====================
|
||
|
|
|
||
|
|
This driver enables the use of a PWM module to drive a fan. It uses the
|
||
|
|
generic PWM interface thus it is hardware independent. It can be used on
|
||
|
|
many SoCs, as long as the SoC supplies a PWM line driver that exposes
|
||
|
|
the generic PWM API.

Description
|
||
|
|
-----------
|
||
|
|
|
||
|
|
The driver implements a simple interface for driving a fan connected to
|
||
|
|
a PWM output. It uses the generic PWM interface, thus it can be used with
|
||
|
|
a range of SoCs. The driver exposes the fan to the user space through
|
||
|
|
the hwmon's sysfs interface.
