Subject: [PATCH 0/5] gpio-fan: regulator support

Hi,

this series adds support for regulator support for the use-case a GPIO
controlled fan also has a switchable power supply.
Patch 1 is the change for the binding, which is based on pwm-fan.
Patch 2-4 is some small cleanup in preparation for regulator support.

Note: Patch 4 can also be suqash into patch 3

Patch 5 is the regulator support by adding RPM support which enabled/disables
the regulator accordingly.

Alexander Stein (5):
  dt-bindings: hwmon: gpio-fan: Add optional regulator support
  hwmon: (gpio-fan) Add missing mutex locks
  hwmon: (gpio-fan) Ensure lock is held during set_fan_speed()
  hwmon: (gpio-fan) Remove unnecessary comment
  hwmon: (gpio-fan) Add regulator support
