Merge tag 'mfd-3.9-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6
Pull MFS updates from Samuel Ortiz:
"This is the MFD pull request for the 3.9 merge window.
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."

+- interrupts : IRQ line for the max8925 chip
+- interrupt-controller: describes the max8925 as an interrupt

+Required properties:

+- 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

+ standard binding for regulators; see regulator.txt.

+- 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

+ and will not provide any enable/disable APIs.

+ * BANK target AB8500 register bank

+ * VALUE decimal or 0x-prefixed hexadecimal
+ *
+ *
+ * User Space notification on AB8500 IRQ
+ * =====================================
+ *
+ * Allows user space entity to be notified when target AB8500 IRQ occurs.
+ * When subscribed, a sysfs entry is created in ab8500.i2c platform device.
+ * One can pool this file to get target IRQ occurence information.
+ *
+ * subscribe to an AB8500 IRQ:
+ * # echo IRQ > <debugfs>/ab8500/irq-subscribe
+ *
+ * unsubscribe from an AB8500 IRQ:
+ * # echo IRQ > <debugfs>/ab8500/irq-unsubscribe
+ *
+ *
+ * AB8500 register formated read/write access
+ * ==========================================
+ *
+ * Read: read data, data>>SHIFT, data&=MASK, output data
+ * [0xABCDEF98] shift=12 mask=0xFFF => 0x00000CDE
+ * Write: read data, data &= ~(MASK<<SHIFT), data |= (VALUE<<SHIFT), write data
+ * [0xABCDEF98] shift=12 mask=0xFFF value=0x123 => [0xAB123F98]
+ *
+ * Usage:
+ * # echo "CMD [OPTIONS] BANK ADRESS [VALUE]" > $debugfs/ab8500/hwreg
+ *
+ * CMD read read access
+ * write write access
+ *
+ * BANK target reg bank
+ * ADDRESS target reg address
+ * VALUE (write) value to be updated
+ *
+ * OPTIONS
+ * -d|-dec (read) output in decimal
+ * -h|-hexa (read) output in 0x-hexa (default)
+ * -l|-w|-b 32bit (default), 16bit or 8bit reg access
+ * -m|-mask MASK 0x-hexa mask (default 0xFFFFFFFF)
+ * -s|-shift SHIFT bit shift value (read:left, write:right)
+ * -o|-offset OFFSET address offset to add to ADDRESS value
+ *
+ * Warning: bit shift operation is applied to bit-mask.
+ * Warning: bit shift direction depends on read or right command.
