Merge tag 'mfd-3.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-next

Pull MFD updates from Samuel Ortiz:
 "For the 3.13 merge window we have a couple of new drivers for the AMS
  AS3722 PMIC and for STMicroelectronics STw481x PMIC.

  Although this is a smaller update than usual, we also have:

   - Device tree support for the max77693 driver

   - linux/of.h inclusion for all DT compatible MFD drivers, to avoid
     build breakage in the future

   - Support for Intel Wildcat Point-LP PCH through the lpc_ich driver

   - A small arizona update for new wm5110 DSP registers and a few fixes

   - A small palmas update as well, including an of_device table
     addition and a few minor fixes

   - Two small mfd-core changes, one including a memory leak fix for
     when mfd_add_device() fails

   - Our usual round of minor cleanups and janitorial fixes"

* ams AS3722 Power management IC.
Required properties:
-------------------
- compatible: Must be "ams,as3722".
- reg: I2C device address.
- interrupt-controller: AS3722 has internal interrupt controller which takes the
interrupt request from internal sub-blocks like RTC, regulators, GPIOs as well
as external input.
- #interrupt-cells: Should be set to 2 for IRQ number and flags.
The first cell is the IRQ number. IRQ numbers for different interrupt source
of AS3722 are defined at dt-bindings/mfd/as3722.h
The second cell is the flags, encoded as the trigger masks from binding document
interrupts.txt, using dt-bindings/irq.
Optional submodule and their properties:
=======================================
Pinmux and GPIO:
===============
Device has 8 GPIO pins which can be configured as GPIO as well as the special IO
functions.
Please refer to pinctrl-bindings.txt in this directory for details of the
common pinctrl bindings used by client devices, including the meaning of the
phrase "pin configuration node".
Following are properties which is needed if GPIO and pinmux functionality
is required:
Required properties:
-------------------
- gpio-controller: Marks the device node as a GPIO controller.
- #gpio-cells: Number of GPIO cells. Refer to binding document
gpio/gpio.txt
Optional properties:
--------------------
Following properties are require if pin control setting is required
at boot.
- pinctrl-names: A pinctrl state named "default" be defined, using the
bindings in pinctrl/pinctrl-binding.txt.
- pinctrl[0...n]: Properties to contain the phandle that refer to
different nodes of pin control settings. These nodes represents
the pin control setting of state 0 to state n. Each of these
nodes contains different subnodes to represents some desired
configuration for a list of pins. This configuration can
include the mux function to select on those pin(s), and
various pin configuration parameters, such as pull-up,
open drain.
Each subnode have following properties:
Required properties:
- pins: List of pins. Valid values of pins properties are:
gpio0, gpio1, gpio2, gpio3, gpio4, gpio5,
gpio6, gpio7
Optional properties:
function, bias-disable, bias-pull-up, bias-pull-down,
bias-high-impedance, drive-open-drain.
Valid values for function properties are:
gpio, interrupt-out, gpio-in-interrupt,
vsup-vbat-low-undebounce-out,
vsup-vbat-low-debounce-out,
voltage-in-standby, oc-pg-sd0, oc-pg-sd6,
powergood-out, pwm-in, pwm-out, clk32k-out,
watchdog-in, soft-reset-in
Regulators:
===========
Device has multiple DCDC and LDOs. The node "regulators" is require if regulator
functionality is needed.
Following are properties of regulator subnode.
Optional properties:
-------------------
The input supply of regulators are the optional properties on the
regulator node. The input supply of these regulators are provided
through following properties:
vsup-sd2-supply: Input supply for SD2.
vsup-sd3-supply: Input supply for SD3.
vsup-sd4-supply: Input supply for SD4.
vsup-sd5-supply: Input supply for SD5.
vin-ldo0-supply: Input supply for LDO0.
vin-ldo1-6-supply: Input supply for LDO1 and LDO6.
vin-ldo2-5-7-supply: Input supply for LDO2, LDO5 and LDO7.
vin-ldo3-4-supply: Input supply for LDO3 and LDO4.
vin-ldo9-10-supply: Input supply for LDO9 and LDO10.
vin-ldo11-supply: Input supply for LDO11.
Optional sub nodes for regulators:
---------------------------------
The subnodes name is the name of regulator and it must be one of:
sd[0-6], ldo[0-7], ldo[9-11]
Each sub-node should contain the constraints and initialization
information for that regulator. See regulator.txt for a description
of standard properties for these sub-nodes.
Additional optional custom properties are listed below.
ams,ext-control: External control of the rail. The option of
this properties will tell which external input is
controlling this rail. Valid values are 0, 1, 2 ad 3.
0: There is no external control of this rail.
1: Rail is controlled by ENABLE1 input pin.
2: Rail is controlled by ENABLE2 input pin.
3: Rail is controlled by ENABLE3 input pin.
Missing this property on DT will be assume as no
external control. The external control pin macros
are defined @dt-bindings/mfd/as3722.h
ams,enable-tracking: Enable tracking with SD1, only supported
by LDO3.
