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" * tag 'mfd-next-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd: (73 commits) mfd: lpc_ich: Mark *_gpio_offsets data with const spmi: rename spmi device lookup helper spmi: document spmi_device_from_of() refcounting dt-bindings: mfd: armltd: Move Arm board syscon's to separate schema mfd: rk8xx: Add support for RK806 power off mfd: rk8xx: Add support for standard system-power-controller property dt-bindings: mfd: rk806: Allow system-power-controller property dt-bindings: mfd: rk8xx: Deprecate rockchip,system-power-controller dt-bindings: mfd: max8925: Convert to DT schema format mfd: Use i2c_get_match_data() in a selection of drivers mfd: Use device_get_match_data() in a bunch of drivers mfd: mc13xxx-spi/wm831x-spi: Use spi_get_device_match_data() mfd: motorola-cpcap: Drop unnecessary of_match_device() call mfd: arizona-spi: Set pdata.hpdet_channel for ACPI enumerated devs mfd: qcom-spmi-pmic: Switch to EXPORT_SYMBOL_GPL() mfd: qcom-spmi-pmic: Fix revid implementation mfd: qcom-spmi-pmic: Fix reference leaks in revid helper mfd: intel-m10-bmc: Change contact for ABI docs mfd: max8907: Convert to use maple tree register cache mfd: max77686: Convert to use maple tree register cache ...
