This patch supplies access to some extra settings provided by the
AB8500 regulator device. We also update some of the existing
initialisation values in accordance with internal ST-Ericsson code
submissions. This single patch was originally a collection of updates
which have been squashed together to aid with clarity.

I tried to apply this but got conflicts - can you please check what's
going on with this vs my topic/ab8500 branch?

It's almost certainly because you're trying to pull the patches in out
of order. This _will_ end in conflicts. Any chance you can start from
01 and work your way though them. I will fixup any that you don't like
on the fly.

Just following up on our IRC discussion I think that the issue here is
you're basing on -rc not on the topic branch - the patches are going in
pretty much in order, there's no meaningful reordering going on. I am
picking things from the start of the several unrelated topics that are
mixed in randomly in the series but there should be no overlap here.
If you just rebase off the topic branch while you do your fixups git
ought to drop the patches for you most of the time.

With this change, Vtvout, Vintcore12, Vaux1, 2 and 3 regulators
support DRMS (Dynamic Regulator Mode Switching) which will
dynamically handle requests for max current consumption from
several consumers and select a suitable regulator mode.

There is already before a register mask in the regulator driver
to allow some bits of a register to be initialized. The register
value is defined in the board configuration. This patch puts a
mask in the board configuration to specify which bits should
actually be altered. The purpose with this patch is to avoid
future mistakes when updating the allowed bits in the regulator
driver.

This looks fine but I'll wait for Linus (plus I suspect it depends on
patch 1). Stopped now due to this.

This patch ensures that many of the recent developments pertaining to
the AB8500 regulator device are propagated out into the public arena.
It aims to update some of the existing initialisation values in
accordance with internal ST-Ericsson code submissions. This single
patch was originally a collection of updates which have been squashed
together to aid with clarity.

The ab8500 MFD should not have knowledge about regulator-
specific platform data like number of regulators and
regulator registers. As the regulator platform data is
about to grow with external regulators, this information
is moved to a new structure provided by the regulator
driver.

Low voltage batteries have a wider voltage range with
lower operating voltages. Some consumers in the platform
may not work with the lower voltages and therefore need
an extra regulator to boost the voltage in this case.
This driver adds support for checking the consumers that
need higher voltage (Vaux1, 2 and 3 regulators, 3 V SIM)
and control the external buck/boost regulator
accordingly.
Note that to utilize the low voltage battery support,
the battery voltage thresholds must be changed. This
applies for the low battery voltage threshold of the
battery manager and the OTP setting for the AB8500
BattOk levels.

Do you want me to merge the ux500 portions into the ux500
maintenance tree?

Lee indicated that splitting them up from the regulator changes causes
bisection issues.

Right.
Ideally just Acks would be really good Linus.
Would you be happy with that?

From: Bengt Jonsson <bengt.g.jonsson@stericsson.com>
Support for HW request is added in the external regulator
driver. A flag in the board configuration can be set to
let HW control the regulator when there is no SW request.
This means that the regulator will be put in high power
mode when there is a SW request and in HW-request mode
otherwise.

record the regulator registers before they are modified by the
ab8500 regulator driver.

Hmmm isn't this an I2C device? Better check with Srinidhi about that

Clean out initialisation that is handled by SoC. Regulator
settings for Vpll (partly), Vsmps1, Vsmps2, Vsmps3 (partly),
Vrf1, Varm, Vape, Vbb, Vmod are cleaned out. They should not
be touched by the kernel.
We also update many of the initialisation values to be more
in-line with the current development efforts of ST-Ericsson
internal engineers.

To: linux-kernel; +Cc: broonie, linus.walleij, Lee Jones
More platforms are to be supported by the AB8500 regulator driver,
so in this patch we prepare for their arrival. Instead of using
the AB8500 settings blindly, we provide an infrastructure where
adding a new platform is as easy as providing a couple of platform
specific data structures.

The external regulator driver checks for old AB8500 HW
to apply a fix. This patch adds a check to see that
it is a AB8500 (not AB8505/AB9540).

There is an awfully small commit blurb for this change. Actually
nothing. We need some explanation, and I want Ola to be in on this
change.

I don't actually know what this is to be honest. I'm just echoing the
internal development process.
Feedback from Ola would be great.

To obtain full AB8505 regulator support, the AB8500 regulator driver
first needs to know its register layout and their initialisation values
for each. That information is provided via a couple of large data
structures which we provide here.

Didn't you just add that supply with the funny name in that other
patch I complained about.... Please merge them into one patch.

See also the patches I squashed down yesterday - it'd really help if
these bugfixes could just get squashed into the original patches when
there's no complex interdependencies in the way.

To obtain full AB8540 regulator support, the AB8500 regulator driver
first needs to know its register layout and their initialisation values
for each. That information is provided via a couple of large data
structures which we provide here.

To: linux-kernel; +Cc: broonie, linus.walleij, Lee Jones
There are a few over-lapping methods for voltage selection operating
in the AB8500 regulator driver currently. This patch removes unused,
unnecessary variables from the regulator_info structures and provides
voltage tables for those regulators which have fixed voltages.

Following a recent move to regulator_list_voltage_table() for
all previous abx500 related platforms this converts all recent
platform updates over too.

The regulator id in the regulator info array should be the same
values as the position of the element within the array. This
patch fixes the mismatches.

From: "xiaomei.zhang" <xiaomei.zhang@stericsson.com>
In former functions, only can set Vaux3 to 2.91V, because the
highest bit of Vaux3 register is put into another register. So
add new expanded functions for Vaux3's operation.

v-amic1 and v-amic2 regulators have dedicated mode registers
and share the same mode bit. This patch adds special handling
for those regulators.

From: Gabriel Fernandez <gabriel.fernandez@stericsson.com>
Instead of using a long list of arguments for registering a new
regulator, the API has changed to accommodate a new structure
which is to contain the necessary runtime configuration. This
patch allows the external regulator to follow suit and continue
to successfully register itself with the Regulator subsystem.

from ab9540, ab8505, ab8540 or ab8500 configuration.

Allow the regulator framework to directly access the time it takes
any given regulator to settle. This saves time and code because
without it we would have to implement a dedication function to read
the value from elsewhere.

The regulator framework now has provisions to read a regulator's
start-up time via the 'enable_time' attribute. So let's remove all
'enable_time'/'delay' duplication and just stick with 'enable_time'
from now on.

The regulator framework offers a generic regulator_list_voltage_table()
function which can directly look-up a regulator's voltage capabilities
using a table provided through the desc structure. This patch ensures
that information is available.

Regulator platform data is now passed though a single structure
as opposed to the old way where four separate struct elements
were required. This patch makes use of the new format.
