Keerthy f0168a9bfd regulator: lp87565: Add support for lp87565 PMIC regulators
The regulators set consists of 4 BUCKs. The output
voltages are configurable and are meant to supply power to the
main processor and other components. The ramp delay is configurable
for all BUCKs. The BUCKs can be configured in single phase or
multiphase modes.

Javier Martinez Canillas 86cf635a31 regulator: Rename files for Maxim PMIC drivers
Most Maxim PMIC regulator drivers are for sub-devices of Multi-Function
Devices with drivers under drivers/mfd. But for many of these, the same
object file name was used for both the MFD and the regulator drivers.

Having 2 different drivers with the same name causes a lot of confusion
to Kbuild, specially if these are built as module since only one module
will be installed and also exported symbols will be undefined due being
overwritten by the other module during modpost.

For example, it fixes the following issue when both drivers are module:

$ make M=drivers/regulator/
  ...
  CC [M]  drivers/regulator//max14577.o
  Building modules, stage 2.
  MODPOST 1 modules
WARNING: "maxim_charger_calc_reg_current" [drivers/regulator//max14577.ko] undefined!
WARNING: "maxim_charger_currents" [drivers/regulator//max14577.ko] undefined!

Javier Martinez Canillas 96173cc6a4 regulator: Rename files for max77686 and max77802 drivers
The max77686 and max77802 regulator drivers are for sub-devices of a MFD
driver for some PMIC blocks. But the same object file name (max77686.o)
was used for both the common MFD driver and the max77686 regulator one.

This confuses kbuild if both drivers are built as module causing the MFD
driver to not be copied when installing the modules.

Also, max77{686,802} are a quite generic name for MFD subdevices drivers
so it is better to rename them to max77{686,802}-regulator like it's the
case for most regulator drivers.

2) No two regulators can be enabled at the same time. Use mutex in

 - 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.

Andrii.Tseglytskyi 40b1936efe 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.

Ashish Jangam f6130be652 regulator: DA9055 regulator driver
This is the Regulator patch for the DA9055 PMIC and has got dependency on
the DA9055 MFD core.

This patch support all of the DA9055 regulators. The output voltages are
fully programmable through I2C interface only. The platform data with regulation
constraints is passed down from the board to the regulator.

This patch is functionaly tested on SMDK6410 board. DA9055 Evaluation board
was connected to the SMDK6410 board.
