- 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.
