Pull LED updates from Lee Jones:
 "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"
