Merge tag 'leds-next-6.6' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/leds
Pull LED updates from Lee Jones:
"Core Frameworks:
- Add new framework to support Group Multi-Color (GMC) LEDs
- Offer an 'optional' API for non-essential LEDs
- Support obtaining 'max brightness' values from Device Tree
- Provide new led_classdev member 'color' (settable via DT and SYFS)
- Stop TTY Trigger from using the old LED_ON constraints
- Statically allocate leds_class
New Drivers:
- Add support for NXP PCA995x I2C Constant Current LED Driver
New Device Support:
- Add support for Siemens Simatic IPC BX-21 to Simatic IPC
Fix-ups:
- Some dependency / Kconfig tweaking
- Move final probe() functions back over from .probe_new()
- Simplify obtaining resources (memory, device data) using unified
API helpers
- Bunch of Device Tree additions, conversions and adaptions
- Fix trivial styling issues; comments
- Ensure correct includes are present and remove some that are not
required
- Omit the use of redundant casts and if relevant replace with better
ones
- Use purpose-built APIs for various actions; sysfs_emit(),
module_led_trigger()
- Remove a bunch of superfluous locking
Bug Fixes:
- Ensure error codes are correctly propagated back up the call chain
- Fix incorrect error values from being returned (missing '-')
- Ensure get'ed resources are put'ed to prevent leaks
- Use correct class when exporting module resources
- Fixing rounding (or lack there of) issues
- Fix 'always false' LED_COLOR_ID_MULTI BUG() check"
