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 * tag 'mfd-next-6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd: (35 commits) MAINTAINERS: Adjust the file entry for the qnap-mcu header dt-bindings: mfd: syscon: Fix ti,j784s4-acspcie-proxy-ctrl compatible dt-bindings: mfd: syscon: Fix al,alpine-sysfabric-service compatible Revert "mfd: axp20x: Allow multiple regulators" dt-bindings: mfd: syscon: Add rk3562 QoS register compatible mfd: syscon: Allow syscon nodes without a "syscon" compatible mfd: syscon: Remove the platform driver support mfd: syscon: Fix race in device_node_get_regmap() dt-bindings: mfd: atmel: Convert to YAML schema dt-bindings: mfd: atmel,at91sam9260: Convert to YAML schema dt-bindings: mfd: sprd,sc2731: Reference sprd,sc2731-efuse bindings mfd: tps65219: Remove unused macros & add regmap.h mfd: tps65219: Use MFD_CELL macros leds: Add LED1202 I2C driver dt-bindings: leds: Add LED1202 LED Controller Documentation:leds: Add leds-st1202.rst mfd: Add support for AAEON UP board FPGA mfd: da9052: Store result from fault_log mfd: intel_soc_pmic_chtdc_ti: Fix invalid regmap-config max_register value mfd: cs42l43: Use devres for remove as well ...

The LED1202 is a 12-channel low quiescent current LED controller
14+
programmable via I2C; The output current can be adjusted separately
15+
for each channel by 8-bit analog and 12-bit digital dimming control.
