Subject: [GIT PULL] LEDs for v6.16
Good morning Linus,
The following changes since commit 0af2f6be1b4281385b618cb86ad946eded089ac8:
Linux 6.15-rc1 (2025-04-06 13:11:33 -0700)
are available in the Git repository at:
git://git.kernel.org/pub/scm/linux/kernel/git/lee/leds.git leds-next-6.16

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
