| 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. |
