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 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
