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). |
