Merge tag 'mfd-3.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-next

Pull MFD update from Samuel Ortiz:
 "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 0998d0631001 ("device-core: Ensure drvdata = NULL when
     no driver is bound")

+* TI - TSC ADC (Touschscreen and analog digital converter)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Required properties:
+- child "tsc"
+	ti,wires: Wires refer to application modes i.e. 4/5/8 wire touchscreen
+		  support on the platform.
+	ti,x-plate-resistance: X plate resistance
+	ti,coordiante-readouts: The sequencer supports a total of 16
+				programmable steps each step is used to
+				read a single coordinate. A single
+                                readout is enough but multiple reads can
+				increase the quality.
+				A value of 5 means, 5 reads for X, 5 for
+				Y and 2 for Z (always). This utilises 12
+				of the 16 software steps available. The
+				remaining 4 can be used by the ADC.
+	ti,wire-config: Different boards could have a different order for
+			connecting wires on touchscreen. We need to provide an
+			8 bit number where in the 1st four bits represent the
+			analog lines and the next 4 bits represent positive/
+			negative terminal on that input line. Notations to
+			represent the input lines and terminals resoectively
+			is as follows:
+			AIN0 = 0, AIN1 = 1 and so on till AIN7 = 7.
+			XP  = 0, XN = 1, YP = 2, YN = 3.
+- child "adc"
+	ti,adc-channels: List of analog inputs available for ADC.
+			 AIN0 = 0, AIN1 = 1 and so on till AIN7 = 7.
+
+Example:
+	tscadc: tscadc@44e0d000 {
+		compatible = "ti,am3359-tscadc";
+		tsc {
+			ti,wires = <4>;
+			ti,x-plate-resistance = <200>;
+			ti,coordiante-readouts = <5>;
+			ti,wire-config = <0x00 0x11 0x22 0x33>;
+		};
+
+		adc {
+			ti,adc-channels = <4 5 6 7>;
+		};
+	}
