This series introduces a driver for the Silergy SY7802 charge pump used
in the BQ Aquaris M5 and X5 smartphones.

The implementation is based on information extracted from downstream as
the datasheet provided by a distributor of the hardware didn't include
any information about the i2c register description.

Changes in v5:
- Fix language in driver description comment
- Unwrap function arguments
- Remove unnecessary empty lines
- Add Acked-by tag to second patch
- Link to v4: https://lore.kernel.org/r/20240616-sy7802-v4-0-789994180e05@apitzsch.eu

Changes in v4:
- Use for_each_available_child_of_node_scoped() to simplify code
- Use dev_err_probe() to be consistent with the other code in
  sy7802_probe()
- Split devm_add_action() into 2 devm_add_action_or_reset() to simplify
  code and balance regulator_enable()
- Link to v3: https://lore.kernel.org/r/20240612-sy7802-v3-0-1e9cc1c79b79@apitzsch.eu

Changes in v3:
- Add R-b tag to first patch
- Extend driver commit message
- Improve readability of defines by using BIT()
- Rename some variables/parameters
  * led_no -> led_id
  * level -> brightness
  * curr -> fled_{strobe,torch}_used_tmp
  * mask -> {flash,torch}_mask
  * i -> child_num
- Restructure structs ("Place th big stuff at the top")
- Declare 'child' on a separate line
- Move multi-line assignments out of declaration block
- Update warning/error messages and comments
- Use gotos to handle error path
- Use devm API to cleanup module's resources
- Init mutex before LED class device is registered to avoid race
  condition
- Link to v2: https://lore.kernel.org/r/20240401-sy7802-v2-0-1138190a7448@apitzsch.eu

Changes in v2:
- bindings: remove unneeded allOf
- bindings: example: move flash-led-controller under i2c node to fix
  check error
- Cc to phone-devel
- Link to v1: https://lore.kernel.org/r/20240327-sy7802-v1-0-db74ab32faaf@apitzsch.eu
