MFD for v6.20

Browse source 
- 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.
