Linus Torvalds d7ab7302f9 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.
