Merge tag 'mfd-next-6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd

Pull mfd updates from Lee Jones:

 - Fix race in device_node_get_regmap() using more extensive locking

 - Remove unused platform driver support for syscon

 - Allow syscon nodes to be registered without a "syscon" compatible
   string

 - Make `platform_data` pointer const in struct mfd_cell

 - Revert support for multiple AXP PMICs to avoid regressions

 - Increase SoundWire attach timeout and use gpiod_set_raw() for GPIO
   operation

 - Store the result from fault_log() for use by other sub-components

 - Fix an invalid regmap-config max_register value

 - Add another Gemini Lake ISA bridge PCI device ID

 - Use devm_register_power_off_handler() to simplify code

 - Add support for QNAP microcontroller units, including LEDs, input,
   and hwmon

 - Use MFD_CELL macros and remove unused code

 - Add support for AAEON UP board FPGA

 - Remove unused includes

 - Fix various typos and compatibility issues in multiple bindings

 - Add new bindings for rk3562 QoS, LED1202, and qcom,tcsr-ipq5424

 - Convert several bindings to YAML schema

 - Update sprd,sc2731 bindings to reference sprd,sc2731-efuse bindings
   directly

 - Fix rohm,bd71815 bindings by correcting resistor values and typos

 - Documentation improvements:
    - Add documentation for LED1202 and qnap-mcu-hwmon
    - Adjust the file entry for the qnap-mcu header in MAINTAINERS
