1 | Kernel driver pwm-fan |
2 | ===================== | |
3 | ||
4 | This driver enables the use of a PWM module to drive a fan. It uses the | |
5 | generic PWM interface thus it is hardware independent. It can be used on | |
6 | many SoCs, as long as the SoC supplies a PWM line driver that exposes | |
7 | the generic PWM API. | |

11 | Description | |
12 | ----------- | |
13 | ||
14 | The driver implements a simple interface for driving a fan connected to | |
15 | a PWM output. It uses the generic PWM interface, thus it can be used with | |
16 | a range of SoCs. The driver exposes the fan to the user space through | |
17 | the hwmon's sysfs interface. |
