Merge tag 'leds-next-6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/leds

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"
