Merge tag 'mfd-next-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd
Pull MFD updates from Lee Jones:
"Core Frameworks:
- Allow all MFD Cell properties to be filled in dynamically at
runtime
- Skip disabled device nodes and continue to look for subsequent
devices
New Device Support:
- Add support for Lunar Lake-M PCI to Intel LPSS PCI
- Add support for Denverton to Intel ICH LPC
New Functionality:
- Add support for Clocks to Texas Instruments TWL* Core
- Add support for Interrupts to STMicroelectronics STM32 Timers
Fix-ups:
- Convert to new devm-* (managed) power-off API
- Remove superfluous code
- Bunch of Device Tree additions, conversions and adaptions
- Simplify obtaining resources (memory, device data) using unified
API helpers
- Trivial coding-style / spelling type clean-ups
- Constify / staticify changes
- Expand or edit on existing documentation
- Convert some Regmap configurations to use the Maple Tree cache
- Apply new __counted_by() annotation to several data structures
containing flexible arrays
- Replace strncpy() with strscpy()
Bug Fixes:
- Remove double put creating reference imbalances
- Ensure headphone/lineout detection gets set when booting with ACPI"
