2019-04-28dt-bindings: hwmon (pwm-fan) Remove dead "cooling-*-state" propertiesRobin Murphy
The old "cooling-{min,max}-state" properties for thermal bindings were ratified to "cooling-{min,max}-level" by commit eb168b70dea5 ("of: thermal: Fix inconsitency between cooling-*-state and cooling-*-level"), which were later removed entirely by commit e04907dbc259 ("dt-bindings: thermal: Remove "cooling-{min|max}-level" properties"). The pwm-fan binding, however, was apparently in-flight in parallel with that ratification, and so managed to introduce an example of the old properties which escaped the scope of the later cleanup and has thus continued to be dutifully copied for new boards despite being useless. Clean up these remaining undocumented anachronisms to minimise any further confusion.

2014-08-04hwmon: Add pwm-fan driverKamil Debski
The pwm-fan driver enables control of fans connected to PWM lines. This driver uses the PWM framework, so it is compatible with all PWM devices that provide drivers through the PWM framework.
