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"
