Hi Mark,
Here is what's left.
I've also split out the "Low Power Battery" patch and squashed a few
of the ab8500-ext fixups back into the original commit as requested.
Kind regards,
Lee

The ABx500 is capable of controlling three external regulator supplies.
Most commonly on and off are supported, but if an external regulator
chipset or power supply supports high-power and low-power mode settings,
we can control those too.

Pass constraint information for recently supported external AB8500
controlled regulators. Also change the start-up initialisation settings
for each of the 3 supported external supplies to low-power, off and
high-power for supply 1, 2 and 3 respectively.

If particular platforms require non-standard initialisation values,
they can use this function to adapt them as required.

v20 HREFs require non-standard configuration of EXT_SUPPLY2 to
function correctly (specific information is commented). Here we make
use of the recently added mechanism to adapt initialisation values
for such use-cases.

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.

The USB regulator is controlled by hardware. The software support
was only needed for early hardware (ED) which is no longer supported.

The purpose of this patch is to guarantee that ab8500-debug will
record the regulator registers before they are modified by the
ab8500 regulator driver.

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.

To obtain full AB9540 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.

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).

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.

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, broonie; +Cc: 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.

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.

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.

The ab*_match[] arrays should be moved out of the way, instead of
bunched in the middle of the initialisation functions. This patch
moves all initialisation code which currently resides above these
arrays down to be grouped with the others. This makes the whole
thing slightly easier to read.

It's kind of a general problem with the AB8500 code but there's an awful
lot of content free trace like this, if there's not adequate trace in
the core for things like that we should add it there.

This looks broken - it's going to interfere with the normal runtime
operation of the device as it's using exactly the same operation to
change the device state. If the hardware doesn't have any support for
suspend mode then the driver shouldn't be implementing this function.

Hrm, this seems like a *lot* of code for simple external enable control
- from the changelog in previous versions and a quick glance at the code
I'd thought it was doing more than that but now I read it properly it's
really just simple enables. Is there really no sharing with the normal
regulators?
Anyway, I applied 1-6.

This appears to be identical to the ab8500, why do we need a separate
set of ops?

Applied everything up to here except "regulator: ab8500-ext: Add support
