Linus Torvalds 3aa78e0cb5 For the 3.11 merge we only have one new MFD driver for the Kontron PLD.
But we also have:
 
 - Support for the TPS659038 PMIC from the palmas driver.
 
 - Intel's Coleto Creek and Avoton SoCs support from the lpc_ich driver.
 
 - RTL8411B support from the rtsx driver.
 
 - More DT support for the Arizona, max8998, twl4030-power and the
   ti_am335x_tsadc drivers.
 
 - The SSBI driver move under MFD.
 
 - A conversion to the devm_* API for most of the MFD drivers.
 
 - The twl4030-power got split from twl-core into its own module.
 
 - A major ti_am335x_adc cleanup, leading to a proper DT support.
 
 - Our regular arizona and wm* updates and cleanups from the Wolfson
   folks.
 
 - A better error handling and initialization, and a regulator subdevice
   addition for the 88pm80x driver.
 
 - A bulk platform_set_drvdata() call removal that's no longer need since
   commit 0998d063.
