Pull MFD updates from Lee Jones:
"Maxim MAX77705:
- Added core MFD driver.
- Added charger driver.
- Added devicetree bindings for the charger and MFD core.
- Added Haptic controller support via the input subsystem.
- Added LED support.
- Added support to simple-mfd-i2c for fuel gauge and hwmon.
Samsung S2MPU05 (Exynos7870 PMIC):
- Added core MFD support.
- Added Regulator support for 21 LDOs and 5 BUCKs.
- Added devicetree bindings for regulators and the PMIC core.
TI TPS65215 & TPS65214:
- Added support to the existing TPS65219 driver.
- Added devicetree bindings.
STMicroelectronics STM32MP25:
- Added support to the stm32-timers MFD driver.
- Added devicetree bindings.
Congatec Board Controller (CGBC):
- Added HWMON support for internal sensors.
- Added support for the conga-SA8 module.
Microchip LAN969X:
- Enabled the at91-usart MFD driver for this architecture.
MediaTek MT6359:
- Added mfd_cell for mt6359-accdet to allow its driver to probe.
Other misc driver updates:
- AXP20X (AXP717): Added AXP717_TS_PIN_CFG register to writeable regs
for temperature sensor configuration.
- SM501: Switched to using BIT() macro to mitigate potential integer
overflows in GPIO functions.
- ENE KB3930: Added a NULL pointer check for off_gpios during probe
to prevent potential dereference.
- SYSCON: Added a check for invalid resource size to prevent issues
from DT misconfiguration.
- CGBC: Corrected signedness issues in cgbc_session_request
- intel_soc_pmic_chtdc_ti / intel_soc_pmic_crc: Removed unneeded
explicit assignment to REGCACHE_NONE.
- ipaq-micro / tps65010: Switched to using str_enable_disable()
helpers for clarity and potential size reduction.
- upboard-fpga: Removed unnecessary ACPI_PTR() annotation.
- max8997: Removed unused max8997_irq_exit() function, using devm_*
helpers instead.
- lp3943: Dropped unused #include <linux/pwm.h> from the header file.
- db8500-prcmu: Removed needless return statements in void APIs.
- qnap-mcu: Replaced commas with semicolons between expressions for
correctness.
- STA2X11: Removed the core MFD driver as the underlying platform
support was removed.
- EZX-PCAP: Removed the unused pcap_adc_sync function.
- PCF50633 (OpenMoko PMIC): Removed the entire driver (core, adc,
gpio, irq) as the underlying s3c24xx platform support was removed.
Devicetree updates:
- Converted fsl,mcu-mpc8349emitx binding to YAML
- Added qcom,msm8937-tcsr compatible
- Added microchip,sama7d65-flexcom compatible
- Added rockchip,rk3528-qos syscon compatible
- Added airoha,en7581-pbus-csr syscon compatible
- Added microchip,sama7d65-ddr3phy syscon compatible
- Added microchip,sama7d65-sfrbu syscon compatible"
