Merge tag 'mfd-next-6.20' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd

Pull MFD updates from Lee Jones:
 "New Support & Features:
   - Add comprehensive support for the ROHM BD72720 PMIC, including core
     MFD, regulator, GPIO, clock gate, RTC, and power-supply drivers
   - Add support for the Rockchip RK801 PMIC, including core MFD and
     regulator drivers
   - Add support for the ROHM BD73900 PMIC by leveraging existing common
     drivers
   - Wire up RTC, hwmon, and input sub-devices for the Apple SMC
     (macsmc) driver
   - Add support for the Delta Networks TN48M switch CPLD via the
     simple-mfd-i2c driver
   - Add support for the TS133 variant to the QNAP MCU driver
   - Provide support for the sama7d65 XLCD controller in the Atmel HLCDC
     driver
   - Add backlight sub-device support to the Congatec Board Controller
     (cgbc)
   - Add Intel Nova Lake-S (NVL-S) PCI IDs to the Intel LPSS driver

  Improvements & Fixes:
   - Implement a "wrapper regmap" for the ROHM BD72720 to handle dual
     I2C slave addresses (0x4b and 0x4c) transparently for child devices
   - Introduce mutex locking around 'mfd_of_node_list' in the MFD core
     to ensure safe concurrent access
   - Fix a potential regulator resource leak in the Arizona core driver
     during boot sequence failures
   - Resolve child device duplication issues on driver rebind for
     Qualcomm PM8xxx and OMAP USB host drivers by using
     of_platform_depopulate()
   - Fix IRQ domain name duplication for the Samsung S2MPG10 by adding a
     unique domain suffix
   - Implement LOCK register handling for the TI TPS65214 variant to
     unlock registers at probe time
   - Fully convert the Loongson-2K BMC driver to use managed resources
     (pcim) and the standard PCI resource API
   - Ensure the Apple SMC mutex is correctly initialized during probe to
     prevent NULL pointer dereferences
   - Expand the ROHM BD71828 power-supply driver to support 9-bit
     register addresses
   - Simplify the Samsung S5M RTC driver by querying platform device IRQ
     resources directly
   - Revert an incorrect read-to-write mask change in the DA9052 SPI
     driver to restore default OTP behavior
   - Fix kernel-doc warnings in the TI TPS6105x driver

- Cleanups & Refactoring
   - Simplify the MFD core by utilizing the scoped
     for_each_child_of_node_scoped() macro and streamlining device_node
     storage
   - Rename ROHM BD71828 IC-specific entities to use consistent prefixes
     for better extensibility
   - Refactor ROHM BD71828 regmap definitions using the
     regmap_reg_range() macro
   - Update the ROHM BD71828 driver to use standard C-style comment
     headers
   - Remove the now unused 'irq_data' field from the Samsung SEC core
     structure
   - Drop unnecessary use of irqd_get_trigger_type() in the Maxim
     MAX77759 driver
   - Default MFD_SPACEMIT_P1 to 'm' if ARCH_SPACEMIT is selected
   - Add missing charger-related registers to the ROHM BD71828 core
     header and Type-C CC registers to the AXP717

  Device Tree Binding Updates:
   - Add new bindings for the ROHM BD72720 PMIC, Rockchip RK801 PMIC,
     Bitmain BM1880 System Controller, and NXP LPC32xx System Control
     Block
   - Clarify trickle-charge terminology and add properties for voltage
     drop (VDR) correction and upper charge limits to the generic
     battery binding
   - Document GPR syscon for NXP S32 SoCs and the smp-memram subnode for
     Aspeed SCU
   - Document numerous new Qualcomm SPMI PMIC compatibles (pmcx0102,
     pmh0101, pmk8850, etc)
   - Add compatibles for the sama7d65 XLCD (Atmel), LAN9691 Flexcom
     (Microchip), and various MediaTek SCPSYS and regulator components
   - Fix a dead link to the audio codec binding in the DA9055
     documentation"
