Merge tag 'mfd-3.7-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6
Pull MFD changes from Samuel Ortiz: "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." 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.

+MAX8907 regulator
+
+Required properties:
+- compatible: "maxim,max8907"
+- reg: I2C slave address
+- interrupts: The interrupt output of the controller
+- mbatt-supply: The input supply for MBATT, BBAT, SDBY, VRTC.
+- in-v1-supply: The input supply for SD1.
+- in-v2-supply: The input supply for SD2.
+- in-v3-supply: The input supply for SD3.
+- in1-supply: The input supply for LDO1.
+...
+- in20-supply: The input supply for LDO20.
+- regulators: A node that houses a sub-node for each regulator within the
+ device. Each sub-node is identified using the node's name (or the deprecated
+ regulator-compatible property if present), with valid values listed below.
+ The content of each sub-node is defined by the standard binding for
+ regulators; see regulator.txt.
+
+Optional properties:
+- maxim,system-power-controller: Boolean property indicating that the PMIC
+ controls the overall system power.
+
+The valid names for regulators are:
+
+ sd1, sd2, sd3, ldo1, ldo2, ldo3, ldo4, ldo5, ldo6, ldo7, ldo8, ldo9, ldo10,
