| 11 | ------------ |
| 12 | This driver implements support for NUVOTON NPCM7XX PWM and Fan Tacho |
| 13 | controller. The PWM controller supports up to 8 PWM outputs. The Fan tacho |
| 14 | controller supports up to 16 tachometer inputs. |
| 15 | |
| 16 | The driver provides the following sensor accesses in sysfs: |
| 17 | |
| 18 | fanX_input ro provide current fan rotation value in RPM as reported |
| 19 | by the fan to the device. |
| 20 | |
| 21 | pwmX rw get or set PWM fan control value. This is an integer |
| 22 | value between 0(off) and 255(full speed). |
