The maximum ramp up and down range of BUCK are shorten
from 64mVstep/us to 16mVstep/us.
Therefore, the RTQ2208_RAMP_VALUE_MAX_uV is modified
to 16000uV in this version.

The MT6360 regulator binding, the example in the MT6360 mfd binding, and
the devicetree users of those bindings are rightfully declaring MT6360
regulator subnodes with non-capital names, and luckily without using the
deprecated regulator-compatible property.
With this driver declaring capitalized BUCKx/LDOx as of_match string for
the node names, obviously no regulator gets probed: fix that by changing
the MT6360_REGULATOR_DESC macro to add a "match" parameter which gets
assigned to the of_match.

The regulator IRQ helper requires caller to provide pointer to IRQ name
which is kept in memory by caller. All other data passed to the helper
in the regulator_irq_desc structure is copied. This can cause some
confusion and unnecessary complexity.
Make the regulator_irq_helper() to copy also the provided IRQ name
information so caller can discard the name after the call to
regulator_irq_helper() completes.

Previously, performing an exclusive get on an already-enabled regulator
resulted in inconsistent state initialization between child and parent
regulators. While the child's counts were updated, its parent's counters
remained unaffected.
Consequently, attempting to disable an already-enabled exclusive regulator
triggered unbalanced disables warnings from its parent regulator.
This commit addresses the issue by propagating the enable state to the
parent regulator using a regulator_enable call. This ensures consistent
state management across the regulator hierarchy, preventing warnings!

Since commit 43a7206b0963 ("driver core: class: make class_register() take

memory, so move the regulator_class structure to be declared at build time
placing it into read-only memory, instead of having to be dynamically

The linear ranges aren't really matching what they should be. Indeed,
the range is inclusive of the min value, so it makes sense the previous
range does NOT include the max step value representing the min value of
the range in question.
Since 3.4V is represented by the decimal value 232, the previous range
max step value should be 231 and not 232.
No expected change in behavior since 3.4V was mapped with step 232 from
the first range but is now mapped with step 232 from the second range.
While at it, remove the incorrect comment from the second range.

range does NOT include the max step value representing the min value of
the range in question.
Since 1.5V is represented by the decimal value 160, the previous range
max step value should be 159 and not 160. Similarly, 3.4V is represented
by the decimal value 236, so the previous range max value should be 235
and not 237.
The only change in behavior this makes is that this actually modeled
the ranges to map step with decimal value 237 with 3.65V instead of
3.4V (the max supported by the HW).

This rewrites the max8998 regulator driver to fetch the dvs
regulators as descriptors. This will likely mostly come from
the device tree since there are no in-tree users of the platform
data, but supplying GPIO descriptor tables from board files is
also possible if needed.

This converts the LP8788 BUCK regulator driver to use GPIO
descriptors.
BUCK1 can use one DVS GPIO and BUCK2 can use two DVS GPIOS,
and no more so just hardcode two GPIO descriptors into
the per-DVS state containers.
Obtain the descriptors from each regulators subdevice.
As there are no in-tree users, board files need to populate
descriptor tables for the buck regulator devices when
they want to use this driver. BUCK1 need a GPIO descriptor
at index 0 and BUCK2 needs two GPIO descriptors at
indices 0 and 1.

The DA9055 regulator was touched before, requireing enable GPIOs
to be passed from pdata.
As we have a device for each regulator, obtain the three gpios
ren ("regulator enable"), rsel ("regulator select") and the
ena ("enable") GPIO associated with the regulator enable
directly from the device and cut down on the amount of
GPIO numbers passed as platform data.
The ren and rsel are just requested as inputs: these are
actually handled by hardware. The ena gpios are driven
actively by the regulator core.
There are no in-tree users, but the regulators are instantiated
from the (undocumed) device tree nodes with "dlg,da9055-regulator"
as compatible, and by simply adding regulator-enable-gpios,
regulator-select-gpios and enable-gpios to this DT node, all
will work as before.

The dvs gpio was still using a legacy number passed from the
platform data. There are no in-tree users of the platform data
so just switch it to a gpio descriptor and obtain it in probe(),
the device tree users will work just as fine with this.
Drop the entirely unused enable_gpio from the platform data
as well. The device tree bindings mentions this but the driver
does not look for it and makes no use of it: it should probably
be implemented properly in a separate patch.

LLVM moved their issue tracker from their own Bugzilla instance to GitHub
issues. While all of the links are still valid, they may not necessarily
show the most up to date information around the issues, as all updates
will occur on GitHub, not Bugzilla.
Another complication is that the Bugzilla issue number is not always the
same as the GitHub issue number. Thankfully, LLVM maintains this mapping
through two shortlinks:
https://llvm.org/bz<num> -> https://bugs.llvm.org/show_bug.cgi?id=<num>
https://llvm.org/pr<num> -> https://github.com/llvm/llvm-project/issues/<mapped_num>
Switch all "https://bugs.llvm.org/show_bug.cgi?id=<num>" links to the
"https://llvm.org/pr<num>" shortlink so that the links show the most up to
date information. Each migrated issue links back to the Bugzilla entry,
so there should be no loss of fidelity of information here.
