These functionalities are actually implemented by NCT6694 firmware, which supports up to 16 voltage sensors, 26 temperature sensors, 10 PWM controllers and 10 tachometers. Do you think implementing these functionalities in the HWMON driver complies with regulations? If the answer is yes, I will drop the IIO and PWM driver and implement everything in the HWMON driver in the next patch. Thanks, Ming
