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 Links: [1] https://doc.awinic.com/doc/20230609wm/8a9a9ac8-1d8f-4e75-bf7a-67a04465c153.pdf [2] https://lore.kernel.org/all/20231006160437.15627-1-ddrokosov@salutedevices.com/ [3] https://lore.kernel.org/all/20231018182943.18700-1-ddrokosov@salutedevices.com/ Dmitry Rokosov (3): leds: aw200xx: support HWEN hardware control dt-bindings: leds: aw200xx: introduce optional enable-gpios property dt-bindings: leds: aw200xx: fix led pattern and add reg constraints George Stark (7): leds: aw200xx: calculate dts property display_rows in the driver dt-bindings: leds: aw200xx: remove property "awinic,display-rows" leds: aw200xx: add delay after software reset leds: aw200xx: enable disable_locking flag in regmap config leds: aw200xx: improve autodim calculation method leds: aw200xx: add support for aw20108 device dt-bindings: leds: awinic,aw200xx: add AW20108 device Martin Kurbanov (1): leds: aw200xx: fix write to DIM parameter .../bindings/leds/awinic,aw200xx.yaml | 100 +++++++++++++----- drivers/leds/Kconfig | 14 ++- drivers/leds/leds-aw200xx.c | 96 ++++++++++++++--- 3 files changed, 159 insertions(+), 51 deletions(-) Reviewed-by: Andy Shevchenko
