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"
