No new drivers this time, but a bunch of fairly big cleanups:
 
 - Roger Quadros worked on a OMAP USBHS and TLL platform data consolidation,
   OMAP5 support and clock management code cleanup.
 
 - The first step of a major sync for the ab8500 driver from Lee Jones. In
   particular, the debugfs and the sysct interfaces got extended and improved.
 
 - Peter Ujfalusi sent a nice patchset for cleaning and fixing the twl-core
   driver, with a much needed module id lookup code improvement.
 
 - The regular wm5102 and arizona cleanups and fixes from Mark Brown.
 
 - Laxman Dewangan extended the palmas APIs in order to implement the palmas
   GPIO and rt drivers.
 
 - Laxman also added DT support for the tps65090 driver.
 
 - The Intel SCH and ICH drivers got a couple fixes from Aaron Sierra and
   Darren Hart.
 
 - Linus Walleij patchset for the ab8500 driver allowed ab8500 and ab9540 based
   devices to switch to the new abx500 pin-ctrl driver.
 
 - The max8925 now has device tree and irqdomain support thanks to Qing Xu.
 
 - The recently added rtsx driver got a few cleanups and fixes for a better
   card detection code path and now also supports the RTS5227 chipset, thanks
   to Wei Wang and Roger Tseng.

* Maxim max8925 Power Management IC
Required parent device properties:
- compatible : "maxim,max8925"
- reg : the I2C slave address for the max8925 chip
- interrupts : IRQ line for the max8925 chip
- interrupt-controller: describes the max8925 as an interrupt
controller (has its own domain)
- #interrupt-cells : should be 1.
- The cell is the max8925 local IRQ number
Optional parent device properties:
- maxim,tsc-irq: there are 2 IRQ lines for max8925, one is indicated in
interrupts property, the other is indicated here.
max8925 consists of a large and varied group of sub-devices:

TPS65090 regulators
Required properties:
- compatible: "ti,tps65090"
- reg: I2C slave address
- interrupts: the interrupt outputs of the controller
- regulators: A node that houses a sub-node for each regulator within the
device. Each sub-node is identified using the node's name, with valid
values listed below. The content of each sub-node is defined by the
standard binding for regulators; see regulator.txt.
dcdc[1-3], fet[1-7] and ldo[1-2] respectively.
- vsys[1-3]-supply: The input supply for DCDC[1-3] respectively.
- infet[1-7]-supply: The input supply for FET[1-7] respectively.
- vsys-l[1-2]-supply: The input supply for LDO[1-2] respectively.
Optional properties:
- ti,enable-ext-control: This is applicable for DCDC1, DCDC2 and DCDC3.
If DCDCs are externally controlled then this property should be there.
- "dcdc-ext-control-gpios: This is applicable for DCDC1, DCDC2 and DCDC3.
If DCDCs are externally controlled and if it is from GPIO then GPIO
number should be provided. If it is externally controlled and no GPIO
entry then driver will just configure this rails as external control
and will not provide any enable/disable APIs.
Each regulator is defined using the standard binding for regulators.
Example:
tps65090@48 {
compatible = "ti,tps65090";
reg = <0x48>;
interrupts = <0 88 0x4>;
vsys1-supply = <&some_reg>;
