Support is already upstream for the somewhat similar KTD2692 flash driver, and this series since v3 also moves its ExpressWire code into a separate library and converts the KTD2692 driver to use that library. Signed-off-by: Duje Mihanović --- Changes in v5: - Split up ExpressWire library and KTD2692 conversion - Rebase on v6.8-rc1 - Link to v4: https://lore.kernel.org/r/20240122-ktd2801-v4-0-33c986a3eb68@skole.hr Changes in v4: - Drop 'extern' keywords in leds-expresswire.h - Add 'expresswire_write_u8' to leds-expresswire.c and use it in the two drivers - Move GPIOLIB dependency to LEDS_EXPRESSWIRE instead of letting clients handle it - Drop time constant macros - Drop delay.h include in ktd2692 - Drop bits.h and delay.h includes in ktd2801 - Link to v3: https://lore.kernel.org/r/20240120-ktd2801-v3-0-fe2cbafffb21@skole.hr Changes in v3: - Split ExpressWire code into library (and convert KTD2692 to use this library) - Rewrite commit messages - Add link to datasheet - Drop of.h include in ktd2801 - Use _cansleep and usleep_range when powering off - Clean up bitwise operation in update_status - Link to v2: https://lore.kernel.org/r/20240118-ktd2801-v2-0-425cf32e0769@skole.hr Changes in v2: - Address maintainer comments: - Drop MODULE_ALIAS - Rename enable-gpios to ctrl-gpios - Rename ktd2801_backlight->desc to ktd2801_backlight->gpiod - Give time constants more descriptive names and note their origins in Samsung driver - Convert to GPIO_ACTIVE_HIGH - Update trailers - Link to v1: https://lore.kernel.org/r/20231005-ktd2801-v1-0-43cd85b0629a@skole.hr --- Duje Mihanović (4): leds: introduce ExpressWire library leds: ktd2692: convert to use ExpressWire library dt-bindings: backlight: add Kinetic KTD2801 binding backlight: Add Kinetic KTD2801 backlight support .../bindings/leds/backlight/kinetic,ktd2801.yaml | 46 ++++++++ MAINTAINERS | 13 +++ drivers/leds/Kconfig | 4 + drivers/leds/Makefile | 3 + drivers/leds/flash/Kconfig | 2 +- drivers/leds/flash/leds-ktd2692.c | 116 +++++-------------- drivers/leds/leds-expresswire.c | 68 +++++++++++ drivers/video/backlight/Kconfig | 7 ++ drivers/video/backlight/Makefile | 1 + drivers/video/backlight/ktd2801-backlight.c | 128 +++++++++++++++++++++ include/linux/leds-expresswire.h | 36 ++++++ 11 files changed, 334 insertions(+), 90 deletions(-) --- base-commit: 6613476e225e090cc9aad49be7fa504e290dd33d change-id: 20231004-ktd2801-0f3883cb59d0 Best regards,
