Merge tag 'leds-next-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/leds
Pull LED updates from Lee Jones:
"Core Frameworks:
- Ensure seldom updated triggers have a brightness value before first
update
New Device Support:
- Add support for Simatic IPC Device BX_59A to IPC LEDs Core
- Add support for Qualcomm PMI8950 PWM to LPG Core
New Functionality:
- Add a bunch of new LED function identifiers
- Add support for High Resolution Timers in LED Trigger Patten
Fix-ups:
- Shift out Audio Trigger to the Sound subsystem
- Convert suitable calls to devm_* managed resources
- Device Tree binding adaptions/conversions/creation
- Remove superfluous code/variables/attributes and simplify overall
- Use/convert to new/better APIs/helpers/MACROs instead of
hand-rolling implementations
Bug Fixes:
- Repair enabling Torch Mode from V4L2 on the second LED
- Ensure PWM is disabled when suspending"
