The Nuvoton BMC NPCM7xx has two identical PWM controller modules, each module has four PWM controller outputs and eight identical Fan controller modules, each module has two Fan controller inputs. The hwmon driver provides sysfs entries through which the user can configure and get the duty cycle between 0 (disable the specific PWM) to 255 of particular PWM output port. The driver support cooling device creation, that could be bound to a thermal zone for the thermal control. The NPCM7xx PWM and Fan driver tested on NPCM750 evaluation board.
