Hello everyone, this is a new version for supporting switching off the pwm-fan regulator. This time it is split into several smaller patches for ease of review. Some organizational changes are inspired/copied by/from pwm_bl. One big drawback form v2 was that there was no distinction bewteen when PWM duty == 0: * keep PWM on inactive level enabled (regulator as well) * disable PWM and regulator This is accomplished by using HWMON_PWM_ENABLE attribute. Documentation is added accordingly.
