MFD bits for the 3.7 merge window. 

As usual we have a few new drivers:
 
 - TI LP8788
 - TI OMAP USB TLL
 - Maxim MAX8907
 - SMSC ECE1099
 - Dialog Semiconductor DA9055
 - A simpler syscon driver that allow us to get rid of the anatop one.
 
 Drivers are also gradually getting Device Tree and IRQ domain support.
 
 The following drivers got DT support:
 - palmas, 88pm860x, tc3589x and twl4030-audio
 
 And those ones now use the IRQ domain APIs:
 - 88pm860x, tc3589x, db8500_prcmu
 
 Also some other interesting changes:
 - Intel's ICH LPC now supports Lynx Point
 - TI's twl4030-audio added a GPO child
 - tps6527 enabled its backlight subdevice
 - The twl6030 pwm driver moved to the new PWM subsystem
 
 And finally a bunch of cleanup and casual fixes for mc13xxx, 88pm860x, palmas,
 ab8500, wm8994, wm5110, max8907 and the tps65xxx family.

Merge tag 'mfd-3.7-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6

Fix up various annoying conflicts: the DT and IRQ domain support came in
twice and was already in 3.6. And then it was apparently rebased.

Guys, DON'T REBASE!

* System Controller Registers R/W driver
System controller node represents a register region containing a set
of miscellaneous registers. The registers are not cohesive enough to
represent as any specific type of device. The typical use-case is for
some other node's driver, or platform-specific code, to acquire a
reference to the syscon node (e.g. by phandle, node path, or search
using a specific compatible value), interrogate the node (or associated
OS driver) to determine the location of the registers, and access the
registers directly.
Required properties:
- compatible: Should contain "syscon".
- reg: the register region can be accessed from syscon
Examples:
gpr: iomuxc-gpr@020e0000 {
compatible = "fsl,imx6q-iomuxc-gpr", "syscon";
reg = <0x020e0000 0x38>;

What is smsc-ece1099?
----------------------
The ECE1099 is a 40-Pin 3.3V Keyboard Scan Expansion
or GPIO Expansion device. The device supports a keyboard
scan matrix of 23x8. The device is connected to a Master
via the SMSC BC-Link interface or via the SMBus.
Keypad scan Input(KSI) and Keypad Scan Output(KSO) signals
are multiplexed with GPIOs.
Interrupt generation
--------------------
Interrupts can be generated by an edge detection on a GPIO
pin or an edge detection on one of the bus interface pins.
Interrupts can also be detected on the keyboard scan interface.
The bus interrupt pin (BC_INT# or SMBUS_INT#) is asserted if
any bit in one of the Interrupt Status registers is 1 and
the corresponding Interrupt Mask bit is also 1.
In order for software to determine which device is the source
of an interrupt, it should first read the Group Interrupt Status Register
to determine which Status register group is a source for the interrupt.
Software should read both the Status register and the associated Mask register,
then AND the two values together. Bits that are 1 in the result of the AND
are active interrupts. Software clears an interrupt by writing a 1 to the
corresponding bit in the Status register.
Communication Protocol
----------------------
- SMbus slave Interface
The host processor communicates with the ECE1099 device
through a series of read/write registers via the SMBus
interface. SMBus is a serial communication protocol between
a computer host and its peripheral devices. The SMBus data
rate is 10KHz minimum to 400 KHz maximum
- Slave Bus Interface
The ECE1099 device SMBus implementation is a subset of the
SMBus interface to the host. The device is a slave-only SMBus device.
The implementation in the device is a subset of SMBus since it
only supports four protocols.
The Write Byte, Read Byte, Send Byte, and Receive Byte protocols are the
only valid SMBus protocols for the device.
- BC-LinkTM Interface
The BC-Link is a proprietary bus that allows communication
between a Master device and a Companion device. The Master
device uses this serial bus to read and write registers
located on the Companion device. The bus comprises three signals,
BC_CLK, BC_DAT and BC_INT#. The Master device always provides the
clock, BC_CLK, and the Companion device is the source for an
independent asynchronous interrupt signal, BC_INT#. The ECE1099
supports BC-Link speeds up to 24MHz.
