Pull MFD update from Samuel Ortiz:
 "For 3.10 we have a few new MFD drivers for:

   - The ChromeOS embedded controller which provides keyboard, battery
     and power management services.  This controller is accessible
     through i2c or SPI.

   - Silicon Laboratories 476x controller, providing access to their FM
     chipset and their audio codec.

   - Realtek's RTS5249, a memory stick, MMC and SD/SDIO PCI based
     reader.

   - Nokia's Tahvo power button and watchdog device.  This device is
     very similar to Retu and is thus supported by the same code base.

   - STMicroelectronics STMPE1801, a keyboard and GPIO controller
     supported by the stmpe driver.

   - ST-Ericsson AB8540 and AB8505 power management and voltage
     converter controllers through the existing ab8500 code.

  Some other drivers got cleaned up or improved.  In particular:

   - The Linaro/STE guys got the ab8500 driver in sync with their
     internal code through a series of optimizations, fixes and
     improvements.

   - The AS3711 and OMAP USB drivers now have DT support.

   - The arizona clock and interrupt handling code got improved.

   - The wm5102 register patch and boot mechanism also got improved."
