- New Support & Features
- Samsung S2MU005: Add support for the Samsung S2MU005 PMIC which includes flash and
RGB LED controllers

driver via SPI
- Improvements & Fixes
- Core: Adjust the brightness sysfs node documentation to clarify that only decimal
values are accepted
- Core: Fix a race condition in the software blink logic when stopping blinking and
setting brightness simultaneously
- Core: Introduce the `multi_max_intensity` sysfs attribute for multicolor LEDs to
support hardware-based global brightness control
- Core: Replace OF-based device lookup with firmware node equivalents to support ACPI
and software nodes
- Core: Return `ENODATA` when reading brightness from hardware-controlled LEDs
- Core: Set the coherent DMA mask to zero for the Samsung PMIC device to suppress
unnecessary "DMA mask not set" messages
- ams OSRAM AS3668: Fix a Kconfig symbol name mismatch in the Makefile that prevented
the driver from being built
- BlinkM: Fix spelling and comment style issues in the driver
- DAC124S085: Declare the SPI command word as `__le16` to ensure correct endianness
and pass sparse checks

LED trigger and other drivers

to a non-zero value

options
- Qualcomm LPG: Optimize memory allocation by combining main structure and channels
into a single allocation using flexible array members
- Texas Instruments LP5860: Add missing `CONFIG_OF` dependency to prevent build
warnings
- TI TPS6131x: Increase the overvoltage protection threshold to 6V to avoid false
triggers with 5V input supplies
- Userspace LEDs (uLEDs): Fix a potential buffer overread by using `strnchr()` for
name string validation
- Userspace LEDs (uLEDs): Return `-EFAULT` on `copy_to_user()` failure to properly
handle read errors
- Cleanups & Refactoring
- Core: Convert various `i2c_device_id` arrays to use named initializers for improved
robustness and readability
- Multi-color Core: Fix incorrect `KernelVersion` and `Date` tags for the
`multi_max_intensity` ABI
- Broadcom BCM63138 / ChromeOS EC: Move `MODULE_DEVICE_TABLE` declarations next to the
ID tables for consistency
- LP5812: Fix a sysfs ABI reference in the documentation
- ST1202: Remove an unused legacy GPIO header include
- Device Tree Binding Updates
- Class: Document the keyboard backlight LED class naming conventions, including a new
scheme for zoned backlights

- IR SPI LED: Add a new 30% duty-cycle value for the IR transmitter used in Xiaomi
Redmi Note 8
- Samsung S2M series: Document the flash LED device bindings for Samsung S2M series
PMICs
- Samsung S2M series: Document the pattern behavior for Samsung S2M series PMIC RGB
LEDs
- Samsung S2MU005: Add device tree bindings for the S2MU005 PMIC, including its flash
and RGB LED sub-devices
