Merge tag 'leds-next-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/leds
Pull LED updates from Lee Jones:
"New Drivers:
- Add support for Intel Cherry Trail Whiskey Cove PMIC LEDs
- Add support for Awinic AW20036/AW20054/AW20072 LEDs
New Device Support:
- Add support for PMI632 LPG to QCom LPG
- Add support for PMI8998 to QCom Flash
- Add support for MT6331, WLEDs and MT6332 to Mediatek MT6323 PMIC
New Functionality:
- Implement the LP55xx Charge Pump
- Add support for suspend / resume to Intel Cherry Trail Whiskey Cove PMIC
- Add support for breathing mode to Intel Cherry Trail Whiskey Cove PMIC
- Enable per-pin resolution Pinctrl in LEDs GPIO
Fix-ups:
- Allow thread to sleep by switching from spinlock to mutex
- Add lots of Device Tree bindings / support
- Adapt relationships / dependencies driven by Kconfig
- Switch I2C drivers from .probe_new() to .probe()
- Remove superfluous / duplicate code
- Replace strlcpy() with strscpy() for efficiency and overflow prevention
- Staticify various functions
- Trivial: Fixing coding style
- Simplify / reduce code
Bug Fixes:
- Prevent NETDEV_LED_MODE_LINKUP from being cleared on rename
- Repair race between led_set_brightness(LED_{OFF,FULL})
- Fix Oops relating to sleeping in critical sections
- Clear LED_INIT_DEFAULT_TRIGGER flag when clearing the current trigger
- Do not leak resources in error handling paths
- Fix unsigned comparison which can never be negative
- Provide missing NULL terminating entries in tables
- Fix misnaming issues"
