Kernel driver npcm750-pwm-fan¶
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).|
