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

+                                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

+                        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.

+* Maxim MAX8998, National/TI LP3974 multi-function device
+
+The Maxim MAX8998 is a multi-function device which includes voltage/current
+regulators, real time clock, battery charging controller and several
+other sub-blocks. It is interfaced using an I2C interface. Each sub-block
+is addressed by the host system using different i2c slave address.
+
+PMIC sub-block
+--------------
+
+The PMIC sub-block contains a number of voltage and current regulators,
+with controllable parameters and dynamic voltage scaling capability.
+In addition, it includes a real time clock and battery charging controller
+as well. It is accessible at I2C address 0x66.
+
+Required properties:
+- compatible: Should be one of the following:
+    - "maxim,max8998" for Maxim MAX8998
+    - "national,lp3974" or "ti,lp3974" for National/TI LP3974.
+- reg: Specifies the i2c slave address of the pmic block. It should be 0x66.
+
+Optional properties:
+- interrupt-parent: Specifies the phandle of the interrupt controller to which
+  the interrupts from MAX8998 are routed to.
+- interrupts: Interrupt specifiers for two interrupt sources.
+  - First interrupt specifier is for main interrupt.
+  - Second interrupt specifier is for power-on/-off interrupt.
+- max8998,pmic-buck1-dvs-gpios: GPIO specifiers for two host gpios used
+  for buck 1 dvs. The format of the gpio specifier depends on the gpio
+  controller.
+- max8998,pmic-buck2-dvs-gpio: GPIO specifier for host gpio used
+  for buck 2 dvs. The format of the gpio specifier depends on the gpio
+  controller.
+- max8998,pmic-buck1-default-dvs-idx: Default voltage setting selected from
+  the possible 4 options selectable by the dvs gpios. The value of this
+  property should be 0, 1, 2 or 3. If not specified or out of range,
+  a default value of 0 is taken.
+- max8998,pmic-buck2-default-dvs-idx: Default voltage setting selected from
+  the possible 2 options selectable by the dvs gpios. The value of this
+  property should be 0 or 1. If not specified or out of range, a default
+  value of 0 is taken.
+- max8998,pmic-buck-voltage-lock: If present, disallows changing of
+  preprogrammed buck dvfs voltages.
+
+Additional properties required if max8998,pmic-buck1-dvs-gpios is defined:
+- max8998,pmic-buck1-dvs-voltage: An array of 4 voltage values in microvolts
+  for buck1 regulator that can be selected using dvs gpio.
+
+Additional properties required if max8998,pmic-buck2-dvs-gpio is defined:
+- max8998,pmic-buck2-dvs-voltage: An array of 2 voltage values in microvolts
+  for buck2 regulator that can be selected using dvs gpio.
+
+Regulators: All the regulators of MAX8998 to be instantiated shall be
+listed in a child node named 'regulators'. Each regulator is represented
+by a child node of the 'regulators' node.
+
+        regulator-name {
+                /* standard regulator bindings here */
+        };
+
+Following regulators of the MAX8998 PMIC block are supported. Note that
+the 'n' in regulator name, as in LDOn or BUCKn, represents the LDO or BUCK
+number as described in MAX8998 datasheet.
+
+        - LDOn
+                  - valid values for n are 2 to 17
+                  - Example: LDO2, LDO10, LDO17
+        - BUCKn
+                  - valid values for n are 1 to 4.
+                  - Example: BUCK1, BUCK2, BUCK3, BUCK4
+
+        - ENVICHG: Battery Charging Current Monitor Output. This is a fixed
+                   voltage type regulator
+
+        - ESAFEOUT1: (ldo19)
+        - ESAFEOUT2: (ld020)
+
+Standard regulator bindings are used inside regulator subnodes. Check
+  Documentation/devicetree/bindings/regulator/regulator.txt
+for more details.

+Texas Instruments TWL family (twl4030) reset and power management module
+
+The power management module inside the TWL family provides several facilities

+binding only supports the complete shutdown of the system after poweroff.
+
+Required properties:
+- compatible : must be "ti,twl4030-power"
