[PATCH RFC 0/3] hwmon: pwm-fan: Add RPM support

Contrary to the gpio-fan the pwm-fan driver isn't easy to setup
with pwmconfig/fancontrol because of the missing hwmon sysfs entry
for actual revolutions per minute. This series adds this feature.

This series based on the recently submitted regulator support.

  Documentation: pwm-fan: Add description for RPM support
