Moving regulator node parsing to regulator driver in place
of parsing it on mfd driver.
The motivation for this change are:
- MFD core driver should not depends on regulator and able
to instantiate device without regulator.
- The API for matching regulators are in regulator core and
it is good that regulator driver only calls this API.
- Regulator specific support should be in regulator driver only
to ease any enhancement/modification for regulators.
- The regulator driver is now registered as mfd sub device and
all regulator registration is done from single probe call.

The TPS65090's DCDC output can also be enable/disable through the
external digital input signal. Add support for enable/disable
either through register access via I2C or through external
control inputs. The external control inputs can be driven through
GPIOs also and hence adding support for passing the GPIO number.

MFD driver registers the regulator driver once per device and
hence it is require to register all regulators in single probe
call.
Following are details of changes done to achieve this:
- Move the regulator enums to mfd header and remove the
tps65090-regulator.h as it does not contain more info.
- Add max regulator and register all regulators even if there
is no regulator init data from platform.
- Convert regulator init data to pointer type in platform data.
- Add input supply name in regulator desc to provide input supply.
- Separate desc information from driver information.
- Disable external control bit to have control through register write.

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.

Regulator platform data handling was mistakenly added to MFD
driver. So we will see build errors if we compile MFD drivers
without CONFIG_REGULATOR. This patch moves regulator platform
data handling from TPS65217 MFD driver to regulator driver.
This makes MFD driver independent of REGULATOR framework so
build error is fixed if CONFIG_REGULATOR is not set.
drivers/built-in.o: In function `tps65217_probe':
tps65217.c:(.devinit.text+0x13e37): undefined reference
to `of_regulator_match'
This patch also fix allocation size of tps65217 platform data.
Current implementation allocates a struct tps65217_board for each
regulator specified in the device tree. But the structure itself
provides array of regulators so one instance of it is sufficient.

Pull workqueue changes from Tejun Heo:
"This is workqueue updates for v3.7-rc1. A lot of activities this
round including considerable API and behavior cleanups.
* delayed_work combines a timer and a work item. The handling of the
timer part has always been a bit clunky leading to confusing
cancelation API with weird corner-case behaviors. delayed_work is
updated to use new IRQ safe timer and cancelation now works as
expected.
* Another deficiency of delayed_work was lack of the counterpart of
mod_timer() which led to cancel+queue combinations or open-coded
timer+work usages. mod_delayed_work[_on]() are added.
These two delayed_work changes make delayed_work provide interface
and behave like timer which is executed with process context.
* A work item could be executed concurrently on multiple CPUs, which
is rather unintuitive and made flush_work() behavior confusing and
half-broken under certain circumstances. This problem doesn't
exist for non-reentrant workqueues. While non-reentrancy check
isn't free, the overhead is incurred only when a work item bounces
across different CPUs and even in simulated pathological scenario
the overhead isn't too high.
All workqueues are made non-reentrant. This removes the
distinction between flush_[delayed_]work() and
flush_[delayed_]_work_sync(). The former is now as strong as the
latter and the specified work item is guaranteed to have finished
execution of any previous queueing on return.
* In addition to the various bug fixes, Lai redid and simplified CPU
hotplug handling significantly.
* Joonsoo introduced system_highpri_wq and used it during CPU
hotplug.
There are two merge commits - one to pull in IRQ safe timer from
tip/timers/core and the other to pull in CPU hotplug fixes from
wq/for-3.6-fixes as Lai's hotplug restructuring depended on them."
Fixed a number of trivial conflicts, but the more interesting conflicts
were silent ones where the deprecated interfaces had been used by new
code in the merge window, and thus didn't cause any real data conflicts.
Tejun pointed out a few of them, I fixed a couple more.

flush[_delayed]_work_sync() are now spurious. Mark them deprecated
and convert all users to flush[_delayed]_work().
If you're cc'd and wondering what's going on: Now all workqueues are
non-reentrant and the regular flushes guarantee that the work item is
not pending or running on any CPU on return, so there's no reason to
use the sync flushes at all and they're going away.
This patch doesn't make any functional difference.

Device have SYS rail which is always ON. It is system power bus. LDO5
and LDO_RTC get powered through this rail internally. Add support for
this rail and make the LDO5/LDO_RTC supply by it. Update document
accordingly.

When the bindings for the TPS6586x regulator were being proposed, I
asserted that DT node naming rules for bus child nodes should also be
applied to nodes inside the TPS6586x regulator node itself. In other
words, that each node providing regulator init data should be named
after the type of object it represented ("regulator") and hence that
some other property was required to indicate which regulator the node
described ("regulator-compatible"). In turn this led to multiple nodes
having the same name, thus requiring node names to use a unit address
to make them unique, thus requiring reg properties within the nodes and
However, subsequent discussion indicates that the rules I was asserting
only applies to standardized bus nodes, and within a device's own node,
the binding can basically do anything sane that it wants.
Hence, this change deprecates the register-compatible property, and
instead uses node names to replace this functionality. This greatly
simplifies the device tree content, making them smaller and more legible.
The code is changed such that old device trees continue to work.

The max voltage will be bounded by min_uV, uV_step and n_voltages, so
remove it to avoid confusing.

This driver supports Fairchild FAN53555 Digitally Programmable
TinyBuck Regulator. The FAN53555 is a step-down switching voltage
regulator that delivers a digitally programmable output from an
input voltage supply of 2.5V to 5.5V. The output voltage is
programmed through an I2C interface.

The lp872x_check_dvs_validity() is used for checking DVS platform data.
If the DVS platform data is not defined, return as error code.
Now, this is unnecessary because the default DVS mode is set in this case.

The lp872x_set_dvs() is used for changing the DVS pin state.
This function works only when the DVS platform data is defined.
So don't assume that DVS data is always valid.
In case the platform data is not defined, the DVS data is set to NULL
for skipping the DVS pin control.
DVS selection and GPIO pin number are used for the LP872x DVS pin control.
For better readability, DVS selection argument is added in lp872x_set_dvs().

The platform specific configuration(general_config) is optional.
However, the DVS settings should be configured explicitly while
loading the driver.
This patch enables configuring the default DVS mode even though
the platform data is not defined.
