Subject: [PATCH v4 00/11] leds: aw200xx: several driver updates

The following patch series includes several updates for the AW200XX LED
driver:
    - some small fixes and optimizations to the driver implementation:
      delays, autodimming calculation, disable_locking regmap flag,
      display_rows calculation in runtime;
    - fix LED device tree node pattern to accept LED names counting not
      only from 0 to f;
    - add missing reg constraints;
    - support HWEN hardware control, which allows enabling or disabling
      AW200XX RTL logic from the main SoC using a GPIO pin;
    - introduce the new AW20108 LED controller, the datasheet for this
      controller can be found at [1].

Changes v4 since v3 at [4]
    - properly handle max_source = 0 situations
    - fix Rob's dt_binding_check alerts

Changes v3 since v2 at [3]:
    - handle all cases during hwen gpio get routine execution
    - rename 'hwen-gpios' to standard 'enable-gpios'
    - properly handle aw200xx_probe_get_display_rows() ret values
    - fix timestamp format in the comments and commit messages
    - expand LEDS_AW200XX config and dt-bindings description
    - describe reg constraints for all compatible variants
    - add Conor's Acked-by tag

Changes v2 since v1 at [2]:
    - rebase on the latest aw200xx changes from lee/leds git repo
    - some commit messages rewording
    - replace legacy gpio_* API with gpiod_* and devm_gpiod_* API
    - rename dt property awinic,hwen-gpio to hwen-gpios according to
      gpiod API
    - use fsleep() instead of usleep_range() per Andy's suggestion
    - add max_brightness parameter to led cdev to restrict
      set_brightness() overflow
    - provide reg constraints as Rob suggested
    - move hwen-gpios to proper dt node in the bindings example
