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. |
