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