  leds: tps6131x: Add support for Texas Instruments TPS6131X flash LED driver (2025-05-22 09:24:51 +0100)

----------------------------------------------------------------
LEDs for v6.16

  * LED Triggers:
    * Allow writing "default" to the sysfs 'trigger' attribute to set an LED to its default trigger
    * If the default trigger is "none", writing "default" will remove the current trigger
    * Updated sysfs ABI documentation for the new "default" trigger functionality
  * LED KUnit Testing:
    * Provide a skeleton KUnit test suite for the LEDs framework
    * Expand the LED class device registration KUnit test to cover more scenarios, including
      `brightness_get` behavior
    * Add KUnit tests for the LED lookup and get API (`led_add_lookup`, `devm_led_get`)
  * LED Flash Class:
    * Add support for setting flash/strobe duration through a new `duration_set` op and
      `led_set_flash_duration()` function, aligning with `V4L2_CID_FLASH_DURATION`
  * Texas Instruments TPS6131x:
    * Add a new driver for the TPS61310/TPS61311 flash LED controllers
    * The driver supports the device's three constant-current sinks for flash and torch modes

  * LED Core:
    * Prevent potential `snprintf()` truncations in LED names by checking for buffer overflows
  * ChromeOS EC LEDs:
    * Avoid a -Wflex-array-member-not-at-end GCC warning by replacing an on-stack flexible structure
      definition with a utility function call
  * Multicolor LEDs:
    * Fix issue where setting multi_intensity while software blinking is active could stop blinking
  * PCA955x LEDs:
    * Avoid potential buffer overflow when creating default labels by changing a field's type to
      `u8` and updating format specifiers
  * PCA995x LEDs:
    * Fix a typo (stray space) in an `of_device_id` entry in the `pca995x_of_match` table
  * Kconfig:
    * Prevent LED drivers from being enabled by default when `COMPILE_TEST` is set

  * Device Property API:
    * Split `device_get_child_node_count()` into a new helper `fwnode_get_child_node_count()` that
      doesn't require a device struct, making the API more symmetrical
  * Driver Modernization (using `fwnode_get_child_node_count()`):
    * Update `leds-pwm-multicolor`, `leds-ncp5623` and `leds-ncp5623` to use the new
      `fwnode_get_child_node_count()` helper, removing their custom implementation
    * As above in the USB Type-C TCPM driver
  * Driver Modernization (using new GPIO setter callbacks):
    * Convert `leds-lgm-sso` to use new GPIO line value setter callbacks which return an integer
      for error handling
    * Convert `leds-pca955x`, `leds-pca9532` and `leds-tca6507` to use new GPIO setter callbacks
  * Documentation:
    * Remove the `.rst` extension for `leds-st1202` in the documentation index for consistency
  * LP8860 LEDs:
    * Use `regmap_multi_reg_write()` for EEPROM writes instead of manual looping
    * Use scoped mutex guards and `devm_mutex_init()` to simplify function exits and ensure
      automatic cleanup
    * Remove default register definitions that are unused when regmap caching is not active
    * Use `devm_regulator_get_enable_optional()` to handle the optional regulator, simplifying
      enabling and removing manual disabling
    * Refactor `lp8860_unlock_eeprom()` to only perform the unlock operation, removing the lock
      part and an unnecessary parameter
    * Use a `devm` action to disable the enable-GPIO, simplifying cleanup and error paths, and
      remove the now-empty `.remove()` function
  * Turris Omnia LEDs:
    * Drop unnecessary commas in terminator entries of `struct attribute` and
      `struct of_device_id` arrays
  * MT6370 RGB LEDs:
    * Use the `LINEAR_RANGE()` for defining `struct linear_range` entries to improve robustness

  * Texas Instruments TPS6131x:
    * Add new devicetree bindings for the TI TPS61310/TPS61311 flash LED driver
