Pull MFD updates from Lee Jones:
 "Changes to existing drivers:
   - Use of managed resources - omap, twl4030, ti_am335x_tscadc
   - Advanced error handling - omap
   - Rework clk management - omap
   - Device Tree (re-)work - tc3589x, pm8921, da9055, sec
   - IRC management overhaul and !BROKEN - pm8921
   - Convert to regmap - ssbi, pm8921
   - Use simple power-management ops - ucb1x00
   - Include file clean-up - adp5520, cs5535, janz, lpc_ich,
      - lpc_sch, max14577, mcp-sa11x0, pcf50633-adc, rc5t583,
      	rdc321x-southbridge, retu, smsc-ece1099, ti-ssp, ti_am335x_tscadc,
	tps65912, vexpress-config, wm8350, ywm8350
   - Various bug fixes across the subsystem
      - NULL/invalid pointer dereference prevention
      - Resource leak mitigation,
      - Variable used initialised
      - Staticise various containers
      - Enforce return value checks

  New drivers/supported devices:
   - Add support for s2mps14 and s2mpa01 to sec
   - Add support for da9063 (v5) to da9063
   - Add support for atom-c2000 to gpio-ich
   - Add support for come-{mbt10,cbt6,chl6} to kempld
   - Add support for da9053 to da9052
   - Add support for itco-wdt (v3) and baytrail to lpc_ich
   - Add new drivers for tps65218, rtsx_usb, bcm590xx

  (Re-)moved drivers:
   - twl4030 ==> drivers/iio
   - ti-ssp  ==> /dev/null"
