regulator: ab8500: Remove unused embedded struct expand_register
Used primarily for the AB8540 which lost support in early 2018.
It is now deemed safe to remove this legacy data structure.

Also fixes W=1 issue:

  drivers/regulator/ab8500.c:88: warning: Function parameter or member 'expand_register' not described in 'ab8500_regulator_info'

regulator: ab8500: Remove AB8505 USB regulator
The USB regulator was removed for AB8500 in
commit 41a06aa738 ("regulator: ab8500: Remove USB regulator").
It was then added for AB8505 in
commit 547f384f33 ("regulator: ab8500: add support for ab8505").

However, there was never an entry added for it in
ab8505_regulator_match. This causes all regulators after it
to be initialized with the wrong device tree data, eventually
leading to an out-of-bounds array read.

Given that it is not used anywhere in the kernel, it seems
likely that similar arguments against supporting it exist for
AB8505 (it is controlled by hardware).

Therefore, simply remove it like for AB8500 instead of adding
an entry in ab8505_regulator_match.

regulator: ab8500: Drop AB8540/9540 support
The AB8540 was an evolved version of the AB8500, but it was never
mass produced or put into products, only reference designs exist.
The upstream support was never completed and it is unlikely that
this will happen so drop the support for now to simplify
maintenance of the AB8500.

ce6f5ea3a7 regulator: ab8500: Provide supply names for the AUX regulators
On some platforms the AUX[1|2|3] regulators are supplied voltage by
a separate regulator. For example on Snowball these are provided by
the EXT3. If we list them here, we can supply voltage to them by
simply listing them in as a consumer of EXT3 in the Snowball case.

Some platforms don't support the AB8500 external regulators, so instead
of having a list of is_<platform>() calls prior to calling
ab8500_ext_regulator_init() from ab8500_regulator_probe(), we can only
register as a platform device on platforms which require them. It means
we also have more control over them when booting with Device Tree.

b4d12a7929 regulator: ab8500: Fix set voltage for AB8540_LDO_AUX3
When setting voltage for AB8540_LDO_AUX3, current code only updates one of
info->voltage_reg and info->expand_register registers which is wrong.
To ensure we set to correct voltage, it always needs to clear or set
expand_register.voltage_mask bit of expand_register.

The function of the expand register bit is the following (from the user manual):
0: VAUX3 output voltage is determined by Vaux3Sel bit settings in register
   VldoCVaux3Sel
1: VAUX3 output voltage is set to 3.05V regardless of Vaux3Sel settings in
   register VldoCVaux3Sel (VldoCVaux3Sel is the register at 0x0421)

So when going to 3.05V, set the expand register bit.
When leaving 3.05V for another voltage, set the target voltage before clearing
the expand register bit.

438e695b87 regulator: ab8500: Get rid of is_enabled from struct ab8500_regulator_info
The intention of this patch is to simplify the code.

Maintain the is_enabled flag is not trivial, it not only needs to set/clear the
flag in disable()/enable() but also needs to set the flag in is_enable() to get
initial status. The only benefit of keeping is_enabled flag is just save a
register read when set_mode(). Remove is_enabled flag makes the code simpler.

This patch also moves ab8500_regulator_is_enabled() close to
ab8500_regulator_[en|dis]able functions.
This is required to avoid a forward declaration because now we call
ab8500_regulator_is_enabled() in ab8500_regulator_set_mode().
This change also makes the code better in readability by moving similar
functions to one place.

3fe5228910 regulator: ab8500: Add mode operation for v-amic
v-amic1 and v-amic2 regulators have dedicated mode registers
and share the same mode bit. This patch adds special handling
for those regulators.

d7607baf32 regulator: ab8500: Add new operations for Vaux3
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.

b080c78a4e regulator: ab8500: Update voltage handling for fixed voltage regulators
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.

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.
