| 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. |
