This patch adds regulator driver for MAX14577 chip. There are two
regulators in this chip:
1. Safeout LDO with constant voltage output of 4.9V. It can be only
enabled or disabled.
2. Current regulator for the charger. It provides current from 90mA up
to 950mA.
Driver supports Device Tree.

regulator: core: Provide a dummy regulator with full constraints

When a system has said that it has fully specified constraints for its
regulators it is still possible that some supplies may be missing,
especially if regulator support has been added to a driver after the
board was integrated. We can handle such situations more gracefully by
providing a dummy regulator.

Unless the caller has specifically indicated that the system design may
not include a given regulator by using regulator_get_optional() or that
it needs its interactions to have an effect using regulator_get_exclusive()
provide a dummy regulator if we can't locate a real one.

The kconfig option REGULATOR_DUMMY that provided similar behaviour for all
regulators has been removed, systems that need it should flag that they
have full constraints instead.

regulator: da9063: Add Dialog DA9063 voltage regulators support.

The driver adds support for the following DA9063 PMIC regulators:
- 11x LDOs (named LDO1 - LDO11),
- 6x buck converters (BCORE1, BCORE2, BPRO, BMEM, BIO, BPERI),

Regulators provide following operations:
- REGULATOR_CHANGE_STATUS and REGULATOR_CHANGE_VOLTAGE for all regulators,
- REGULATOR_CHANGE_MODE for LDOs and buck converters, where:
- LDOs allow REGULATOR_MODE_NORMAL and REGULATOR_MODE_STANDBY,
- buck converters allow REGULATOR_MODE_FAST, REGULATOR_MODE_NORMAL
and REGULATOR_MODE_STANDBY,
- REGULATOR_CHANGE_CURRENT for buck converters (current limits).

The driver generates REGULATOR_EVENT_OVER_CURRENT for LDO3, LDO4, LDO7, LDO8
and LDO11.

Internally, PMIC provides two voltage configurations for normal and suspend
system state for each regulator. The driver switches between those on
suspend/wake-up to provide quick and fluent output voltage change.

This driver requires MFD core driver for operation.

regulator: Introduce TI Adaptive Body Bias(ABB) on-chip LDO driver

Adaptive Body Biasing (ABB) modulates transistor bias voltages
dynamically in order to optimize switching speed versus leakage.

Texas Instruments' SmartReflex 2 technology provides support for this
power management technique with Forward Body Biasing (FBB) and Reverse
Body Biasing (RBB). These modulate the body voltage of transistor
cells or blocks dynamically to gain performance and reduce leakage.
TI's SmartReflex white paper[1] has further information for usage in
conjunction with other power management techniques.

The application of FBB/RBB technique is determined for each unique
device in some process nodes, whereas, they are mandated on other
process nodes.

In a nutshell, ABB technique is implemented on TI SoC as an on-chip
LDO which has ABB module controlling the bias voltage. However, the
voltage is unique per device. These vary per SoC family and the manner
in which these techniques are used may vary depending on the Operating
Performance Point (OPP) voltage targeted. For example:
OMAP3630/OMAP4430: certain OPPs mandate usage of FBB independent of
devices.
OMAP4460/OMAP4470: certain OPPs mandate usage of FBB, while others may
optionally use FBB or optimization with RBB.
OMAP5: ALL OPPs may optionally use ABB, and ABB biasing voltage is
influenced by vset fused in s/w and requiring s/w override of
default values.

Further, two generations of ABB module are used in various TI SoCs.
They have remained mostly register field compatible, however the
register offset had switched between versions.

We introduce ABB LDO support in the form of a regulator which is
controlled by voltages denoting the desired Operating Performance
Point which is targeted. However, since ABB transition is part of OPP
change sequence, the sequencing required to ensure sane operation
w.r.t OPP change is left to the controlling driver (example: cpufreq
SoC driver) using standard regulator operations.

The driver supports all ABB modes and ability to override ABB LDO vset
control efuse based ABB mode detection etc.

Current implementation is heavily influenced by the original patch
series [2][3] from Mike Turquette. However, the current implementation
supports only device tree based information.
