The Maxim MAX25014 is an automotive grade backlight driver IC. Its datasheet can be found at [1].
With its integrated boost controller, it can power 4 channels (led strings) and has a number of different modes using pwm and or i2c. Currently implemented is only i2c control. link: https://www.analog.com/media/en/technical-documentation/data-sheets/MAX25014.pdf [1] Signed-off-by: Maud Spierings <maudspieri...@gocontroll.com> --- Changes in v3: - fixed commit message type intgrated -> integrated - added maximum and description to maxim,iset-property - dropped unused labels and pinctrl in bindings example - put the compatible first in the bindings example and dts - removed brackets around defines - removed the leftover pdata struct field - removed the initial_brightness struct field - Link to v2: https://lore.kernel.org/r/20250819-max25014-v2-0-5fd7aeb14...@gocontroll.com Changes in v2: - Remove leftover unused property from the bindings example - Complete the bindings example with all properties - Remove some double info from the maxim,iset property - Remove platform_data header, fold its data into the max25014 struct - Don't force defines to be unsigned - Remove stray struct max25014 declaration - Remove chipname and device from the max25014 struct - Inline the max25014_backlight_register() and strings_mask() functions - Remove CONFIG_OF ifdef - Link to v1: https://lore.kernel.org/r/20250725-max25014-v1-0-0e8cce920...@gocontroll.com --- Maud Spierings (4): dt-bindings: backlight: Add max25014 bindings backlight: add max25014atg backlight arm64: dts: freescale: moduline-display-av101hdt-a10: add backlight arm64: dts: freescale: moduline-display-av123z7m-n17: add backlight .../bindings/leds/backlight/maxim,max25014.yaml | 81 +++++ MAINTAINERS | 6 + ...x8p-ml81-moduline-display-106-av101hdt-a10.dtso | 21 ++ ...x8p-ml81-moduline-display-106-av123z7m-n17.dtso | 19 +- drivers/video/backlight/Kconfig | 7 + drivers/video/backlight/Makefile | 1 + drivers/video/backlight/max25014.c | 394 +++++++++++++++++++++ 7 files changed, 528 insertions(+), 1 deletion(-) --- base-commit: 8f21d9da46702c4d6951ba60ca8a05f42870fe8f change-id: 20250626-max25014-4207591e1af5 Best regards, -- Maud Spierings <maudspieri...@gocontroll.com>
