multi-level ifs which mirror a switch statement. Refactor to use a switch

The LP8756x family has a single output 4-phase regulator
configuration. Add support for the same. The control
lies in the master buck which is buck0 for 4-phase
configuration. Enable/disable/voltage set happen via
buck0 registers.

The conversion here is really trivial: just a bunch of title
markups and very few puntual changes is enough to make it to
be parsed by Sphinx and generate a nice html.
The conversion is actually:
- add blank lines and identation in order to identify paragraphs;
- fix tables markups;
- add some lists markups;
- mark literal blocks;
- adjust title markups.
At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

This finalizes the descriptor conversion of the MAX8952 driver
by letting the VID0 and VID1 GPIOs be fetched from descriptors.
Both VID0 and VID1 must be supplied for the VID selection to work,
I add some code to preserve the semantics that if only one of
the two VID gpios is supplied, it will be initialized to low.
This might be a bit overzealous, but I want to preserve any
implicit semantics.
This is currently only used by device tree in-kernel but it is
still also possible to supply the same GPIOs using a machine
descriptor table if a board file is used.
Ideally this should be phased over to using gpio-regulator.c
that does the same thing, but it might require some refactoring
and needs testing on real hardware.

This converts the Wolfson Micro WM831x DCDC converter to use
a GPIO descriptor for the GPIO driving the DVS pin.
There is just one (non-DT) machine in the kernel using this, and
that is the Wolfson Micro (now Cirrus) Cragganmore 6410 so we
patch this board to pass a descriptor table and fix up the driver
accordingly.

Lockdep reports the following issue on my setup:
Possible unsafe locking scenario:
CPU0 CPU1
---- ----
lock((work_completion)(&(&rdev->disable_work)->work));
lock(regulator_list_mutex);
lock((work_completion)(&(&rdev->disable_work)->work));
lock(regulator_list_mutex);
The problem is that regulator_unregister takes the
regulator_list_mutex and then calls flush_work on disable_work. But
regulator_disable_work calls regulator_lock_dependent which will
also take the regulator_list_mutex. Resulting in a deadlock if the
flush_work call actually needs to flush the work.
Fix this issue by moving the flush_work outside of the
regulator_list_mutex. The list mutex is not used to guard the point at
which the delayed work is queued, so its use adds no additional safety.

During several error paths in the function
regulator_set_voltage_unlocked() the value of 'ret' can take on negative
error values. However, in calls that go through the 'goto out' statement,
this return value is lost and return 0 is used instead, indicating a
'pass'.
There are several cases where this function should legitimately return a
fail instead of a pass: one such case includes constraints check during
voltage selection in the call to regulator_check_voltage(), which can
have -EINVAL for the case when an unsupported voltage is incorrectly
requested. In that case, -22 is expected as the return value, not 0.

commit e5e21f70bf ("regulator: core: Take lock before applying system

to silence a lockdep warning during regulator_register().
However, we are not supposed to need locks at this point as the regulator
is in the process of being registered, so there should be no possibility
of concurrent access.
Instead, remove the unnecessary locking and simply drop the lockdep
annotation, since it is no longer valid.

One of the more common cases of allocation size calculations is finding

struct foo {
int stuff;
struct boo entry[];

size = sizeof(struct foo) + count * sizeof(struct boo);
instance = alloc(size, GFP_KERNEL)
Instead of leaving these open-coded and prone to type mistakes, we can

instance = alloc(struct_size(instance, entry, count), GFP_KERNEL)
Notice that, in this case, variable size is not necessary, hence it is

Currently rdev is dereferenced when assigning desc before rdev is null
checked, this is leading to static analysis warnings. However, rdev
can never be null, so the null check is redundant and can be removed.

commit e5e21f70bf ("regulator: core: Take lock before applying system
load") took the regulator lock before calling drms_uA_update() in order
to silence a lockdep warning during regulator_register().
However, we are not supposed to need locks at this point as the regulator
is in the process of being registered, so there should be no possibility
of concurrent access.
Instead, remove the unnecessary locking and simply drop the lockdep
annotation, since it is no longer valid.

read ROHM BD71837 / BD71847 specific device tree bindings for
controlling the PMIC shutdown/reset states and voltages for
different HW states. The PMIC was designed to be used with NXP
i.MX8 SoC and it supports SNVS low power state which seems to
be typical for NXP i.MX SoCs. However, when SNVS is used we must
not allow SW to control enabling/disabling those regulators which
are crucial for system to boot as there is a HW limitation which
causes SW controlled regulators to be kept shut down after SNVS
reset.
Allow setting the SNVS to be used as reset target state and allow
marking those regulators which are critical for boot.

for enable GPIOs instead of a global GPIO number, delete the support
for passing GPIO numbers in, and we get a cleanup and size reduction

This pushes the handling of inversion semantics and open drain
settings to the GPIO descriptor and gpiolib. All affected board
files are also augmented.
This is especially nice since we don't have to have any
confusing flags passed around to the left and right littering
the fixed and GPIO regulator drivers and the regulator core.
It is all just very straight-forward: the core asks the GPIO
line to be asserted or deasserted and gpiolib deals with the
rest depending on how the platform is configured: if the line
is active low, it deals with that, if the line is open drain,
it deals with that too.

This converts the GPIO regulator driver to use decriptors only.
We have to let go of the array gpio handling: the fetched descriptors
are handled individually anyway, and the array retrieveal function
does not make it possible to retrieve each GPIO descriptor with
unique flags. Instead get them one by one.
We request the "enable" GPIO separately as before, and make sure
that this line is requested as nonexclusive since enable lines can
be shared and the regulator core expects this.
Most users of the GPIO regulator are using device tree.
There are two boards in the kernel using the gpio regulator from a
non-devicetree path: PXA hx4700 and magician. Make sure to switch
these over to use descriptors as well.
