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 v5 since v4 at [5]:
- make several lowercase->uppercase renaming suggested by Lee Jones
- change aw200xx_probe_get_display_rows() return value type from
boolean to integer and propagate error return values to the
dev_err_probe()
- fix some grammar problems
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
