Pull MFD updates from Lee Jones:
 "Changes to existing drivers:
   - increase DT coverage: arizona, mc13xxx, stmpe-i2c, syscon,
     sun6i-prcm
   - regmap use of and/or clean-up: tps65090, twl6040
   - basic renaming: max14577
   - use new cpufreq helpers: db8500-prcmu
   - increase regulator support: stmpe, arizona, wm5102
   - reduce legacy GPIO overhead: stmpe
   - provide necessary remove path: bcm590xx
   - expand sysfs presence: kempld
   - move driver specific code out to drivers: rtc-s5m, arizona
   - clk handling: twl6040
   - use managed (devm_*) resources: ipaq-micro
   - clean-up/remove unused/duplicated code: tps65218, sec, pm8921,
     abx500-core, db8500-prcmu, menelaus
   - build/boot/sematic bug fixes: rtsx_usb, stmpe, bcm590xx, abx500,
     mc13xxx, rdc321x-southbridge, mfd-core, sec, max14577, syscon,
     cros_ec_spi
   - constify stuff: sm501, tps65910, tps6507x, tps6586x, max77686,
     max8997, kempld, max77693, max8907, rtsx_usb, db8500-prcmu,
     max8998, wm8400, sec, lp3943, max14577, as3711, omap-usb-host,
     ipaq-micro

  Support for new devices:
   - add support for max77836 into max14577
   - add support for tps658640 into tps6586x
   - add support for cros-ec-i2c-tunnel into cros_ec
   - add new driver for rtsx_usb_sdmmc and rtsx_usb_ms
   - add new driver for axp20x
   - add new driver for sun6i-prcm
   - add new driver for ipaq-micro"
