Pull MFD updates from Lee Jones:
"Core Frameworks:
- Add support for registering devices via MFD cells to Simple MFD (I2C)
New Drivers:
- Add support for Renesas Synchronization Management Unit (SMU)
New Device Support:
- Add support for N5010 to Intel M10 BMC
- Add support for Cannon Lake to Intel LPSS ACPI
- Add support for Samsung SSG{1,2} to ST-Ericsson's U8500 family
- Add support for TQMx110EB and TQMxE40x to TQ-Systems PLD TQMx86
New Functionality:
- Add support for GPIO to Intel LPC ICH
- Add support for Reset to Texas Instruments TPS65086
Fix-ups:
- Trivial, sorting, whitespace, renaming, etc; mt6360-core, db8500-prcmu-regs, tqmx86
- Device Tree fiddling; syscon, axp20x, qcom,pm8008, ti,tps65086, brcm,cru
- Use proper APIs for IRQ map resolution; ab8500-core, stmpe, tc3589x, wm8994-irq
- Pass 'supplied-from' property through axp288_fuel_gauge via swnode
- Remove unused file entry; MAINTAINERS
- Make interrupt line optional; tps65086
- Rename db8500-cpuidle driver symbol; db8500-prcmu
- Remove support for unused hardware; tqmx86
- Provide a standard LPC clock frequency for unknown boards; tqmx86
- Remove unused code; ti_am335x_tscadc
- Use of_iomap() instead of ioremap(); syscon
Bug Fixes:
- Clear GPIO IRQ resource flags when no IRQ is set; tqmx86
- Fix incorrect/misleading frequencies; db8500-prcmu
- Mitigate namespace clash with other GPIOBASE users"
