[PATCH 0/4] Add OF support for Microchip emc2305 fan controller

[florin . leotescu]

From: Florin Leotescu <florin.leotescu@xxxxxxx>

This patch series is a complementary follow-up to the previously accepted
patch series that added initial Device Tree (OF) support for the Microchip
EMC2305 fan controller.

This series builds on that foundation and introduces the actual implementation
of PWM channel configuration based on DT properties:

- Adds three new attributes to the driver data structures to support
  PWM frequency, polarity and output configuration.
- Implements parsing of child nodes and 'pwms' phandle arguments from the
  Device Tree and applies the corresponding per-channel configuration.
- Prevents the PWM value from being set to a thermal-state-based minimum
  during driver probe when the temperature exceeds trip points.
