Subject: [PATCH v5 0/3] Add OF support for Microchip emc2305 fan controller

From: Florin Leotescu <florin.leotescu@....com>

This patch series add initial OF support for Microchip emc2305 fan controller.

Changes since v4:
- Corrected quotes to have a consistent definition.
- Corrected DTS coding style as recommended by Krzysztof Kozlowski.
- Updated pwms phandle to include pwm frequency, pwm polarity and pwm output,
  as recommended by Guenter Roeck and skipped the pwm channel as recommended by Krzysztof Kozlowski.
- Documented the pwms args in #pwm-cells description.
- Updated pwms phandle in dt-binding example to include pwm frequency and 
  use PWM_POLARITY_INVERTED macro to inverse the PWM polarity. 

Changes since v3:
- Removed thermal_cooling_device_register_fail label since is no longer needed
  and replaced goto with imediate return, as recommended by Guenter Roeck. 
- Redefined compatible property in dt-binding, as recommended by Frank Li.
- Updated driver of compatible list.
- Renamed node name in the dt-binding example, as recommended by Connor Dooley.
- Corrected dt-binding commit subject.
- Added dt-binding fan descriptions and $ref to fan schema, 
  as Connor Dooley & Krzysztof Kozlowski recommended.
  Used similar as on maxim,max6639 and nuvoton,nct7363. 
- Updated dt-binding example.

Changes since v2:
- Removed the introduction of new properties for now and we only 
  enable basic OF support.
- Link to previous version:
