Pull MFD updates from Lee Jones:
 "Core Framework:
   - Add support for Software Nodes to MFD Core
   - Remove support for Device Properties from MFD Core
   - Use standard APIs in MFD Core

  New Drivers:
   - Add support for ROHM BD9576MUF and BD9573MUF PMICs
   - Add support for Netronix Embedded Controller, PWM and RTC
   - Add support for Actions Semi ATC260x PMICs and OnKey

  New Device Support:
   - Add support for DG1 PCIe Graphics Card to Intel PMT
   - Add support for ROHM BD71815 PMIC to ROHM BD71828
   - Add support for Tolino Shine 2 HD to Netronix Embedded Controller
   - Add support for AX10 BMC Secure Updates to Intel M10 BMC

  Removed Device Support:
   - Remove Arizona Extcon support from MFD
   - Remove ST-E AB8500 Power Supply code from MFD
   - Remove AB3100 altogether

  New Functionality:
   - Add support for SMBus and I2C modes to Dialog DA9063
   - Switch to using Software Nodes in Intel (various)

  New/converted Device Tree bindings:
   - rohm bd71815-pmic, rohm bd9576-pmic, netronix ntxec, actions
     atc260x, ricoh rn5t618, qcom pm8xxx

- Fix-ups:
   - Fix error handling/path; intel_pmt
   - Simplify code; rohm-bd718x7, ab8500-core, intel-m10-bmc
   - Trivial clean-ups (reordering, spelling); rohm-generic, rn5t618,
     max8997
   - Use correct data-type; db8500-prcmu
   - Remove superfluous code; lp87565, intel_quark_i2c_gpi, lpc_sch, twl
   - Use generic APIs/defines; lm3533-core, intel_quark_i2c_gpio
   - Regmap related fix-ups; intel-m10-bmc, sec-core
   - Reorder resource freeing during remove; intel_quark_i2c_gpio
   - Make table indexing more robust; intel_quark_i2c_gpio
   - Fix reference imbalances; arizona-irq
   - Staticify and (un)constify things; arizona-spi, stmpe, ene-kb3930,
     intel-lpss-acpi, intel-lpss-pci, atc260x-i2c, intel_quark_i2c_gpio

  Bug Fixes:
   - Fix incorrect (register) values; intel-m10-bmc
   - Kconfig related fixes; ABX500_CORE
   - Do not clear the Auto Reload Register; stm32-timers"
