Hello,

This series adds support for the Kinetic KTD2801 LED backlight driver
IC found in samsung,coreprimevelte.

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.

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
