For the 3.11 merge we only have one new MFD driver for the Kontron PLD.

Browse source 
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.

This is the core driver for the PLD (Programmable Logic Device) found
on some Kontron ETX and COMexpress (ETXexpress) modules. The PLD
device may provide functions like watchdog, GPIO, UART and I2C bus.
The following modules are supported:
* COMe-bIP#
* COMe-bPC2 (ETXexpress-PC)
* COMe-bSC# (ETXexpress-SC T#)
* COMe-cCT6
* COMe-cDC2 (microETXexpress-DC)
* COMe-cPC2 (microETXexpress-PC)
* COMe-mCT10
* ETX-OH
This driver can also be built as a module. If so, the module
will be called kempld-core.
