Linus Walleij d619bc143e regulator: AB3100 support
This adds support for the regulators found in the AB3100
Mixed-Signal IC.

It further also defines platform data for the ST-Ericsson
U300 platform and extends the AB3100 MFD driver so that
platform/board data with regulation constraints and an init
function can be passed down all the way from the board to
the regulators.

Sascha Hauer 295c08bc69 regulator: Add Freescale MC13783 driver
This driver provides basic support for the voltage regulators
integrated into the Freescale MC13783 PMIC. It is currently
only possible to enable/disable outputs, not to actually
set the voltage.

Mark Brown e4ee831f94 regulator: Add WM831x DC-DC buck convertor support
The WM831x series of devices all have 3 DC-DC buck convertors. This
driver implements software control for these regulators via the
regulator API.  Use with split hardware/software control of individual
regulators is not supported, though regulators not controlled by
software may be controlled via the hardware control interfaces.

Marek Szyprowski 0cbdf7bce5 LP3971 PMIC regulator driver (updated and combined version)
This patch adds regulator drivers for National Semiconductors LP3971 PMIC.
This LP3971 PMIC controller has 3 DC/DC voltage converters and 5 low
drop-out (LDO) regulators. LP3971 PMIC controller uses I2C interface.

Mike Rapoport 1d98cccf7f regulator: add userspace-consumer driver
The userspace-consumer driver allows control of voltage and current
regulator state from userspace. This is required for fine-grained
power management of devices that are completely controller by userspace
applications, e.g. a GPS transciever connected to a serial port.

Robert Jarzmik 55f4fa4e33 Maxim 1586 regulator driver
The Maxim 1586 regulator is a voltage regulator with 2
voltage outputs, specially suitable for Marvell PXA
chips. One output is in the range of required VCC_CORE by
the PXA27x chips, the other in the VCC_USIM required as well
by PXA27x chips.

The chip is controlled through the I2C bus.

David Brownell fa16a5c13a regulator: twl4030 regulators
Support most of the LDO regulators in the twl4030 family chips.
In the case of LDOs supporting MMC/SD, the voltage controls are
used; but in most other cases, the regulator framework is only
used to enable/disable a supplies, conserving power when a given
voltage rail is not needed.

The drivers/mfd/twl4030-core.c code already sets up the various
regulators according to board-specific configuration, and knows
that some chips don't provide the full set of voltage rails.

The omitted regulators are intended to be under hardware control,
such as during the hardware-mediated system powerup, powerdown,
and suspend states.  Unless/until software hooks are known to
be safe, they won't be exported here.

These regulators implement the new get_status() operation, but
can't realistically implement get_mode(); the status output is
effectively the result of a vote, with the relevant hardware
inputs not exposed.

Support for configuration of the suspend and hibernate mode behaviour
of the regulators is not yet included.
