Pull MFD updates from Lee Jones:
 "New Drivers:
   - Add support for initialising shared (between children) Regmaps
   - Add support for Kontron SL28CPLD
   - Add support for ENE KB3930 Embedded Controller
   - Add support for Intel FPGA PAC MAX 10 BMC

  New Device Support:
   - Add support for Power to Ricoh RN5T618
   - Add support for UART to Intel Lakefield
   - Add support for LP87524_Q1 to Texas Instruments LP87565

  New Functionality:
   - Device Tree; ene-kb3930, sl28cpld, syscon, lp87565, lp87524-q1
   - Use new helper dev_err_probe(); madera-core, stmfx, wcd934x
   - Use new GPIOD API; dm355evm_msp
   - Add wake-up capability; sprd-sc27xx-spi
   - Add ACPI support; kempld-core

  Fix-ups:
   - Trivial (spelling/whitespace); Kconfig, ab8500
   - Fix for unused variables; khadas-mcu, kempld-core
   - Remove unused header file(s); mt6360-core
   - Use correct IRQ flags in docs; act8945a, gateworks-gsc, rohm,bd70528-pmic
   - Add COMPILE_TEST support; asic3, tmio_core
   - Add dependency on I2C; SL28CPLD

  Bug Fixes:
   - Fix memory leak(s); sm501
   - Do not free regmap_config's 'name' until exit; syscon"
