Using lowercase for the buck and ldo nodenames is preferred, as
evidenced e.g. in [1].
Convert the example here to lowercase before we add any bindings
describing the s2mpg1x regulators that will enforce the spelling.

The S2MPG10 PMIC is a Power Management IC for mobile applications with
buck converters, various LDOs, power meters, RTC, clock outputs, and
additional GPIO interfaces.
It has 10 buck and 31 LDO rails. Several of these can either be
controlled via software (register writes) or via external signals, in
particular by:
* one out of several input pins connected to a main processor's:
* GPIO pins
* other pins that are e.g. firmware- or power-domain-controlled
without explicit driver intervention
* a combination of input pins and register writes.
Control via input pins allows PMIC rails to be controlled by firmware,
e.g. during standby/suspend, or as part of power domain handling where
otherwise that would not be possible. Additionally toggling a pin is
faster than register writes, and it also allows the PMIC to ensure that
any necessary timing requirements between rails are respected
automatically if multiple rails are to be enabled or disabled quasi
simultaneously.
While external control via input pins appears to exist on other
versions of this PMIC, there is more flexibility in this version, in
particular there is a selection of input pins to choose from for each
rail (which must therefore be configured accordingly if in use),
whereas other versions don't have this flexibility.
Add documentation related to the regulator (buck & ldo) parts like
devicetree definitions, regulator naming patterns, and additional
properties.
S2MPG10 is typically used as the main-PMIC together with an S2MPG11
PMIC in a main/sub configuration, hence the datasheet and the binding
both suffix the rails with an 'm'.

The S2MPG11 PMIC is a Power Management IC for mobile applications with
buck converters, various LDOs, power meters, NTC thermistor inputs, and
additional GPIO interfaces. It typically complements an S2MPG10 PMIC in
a main/sub configuration as the sub-PMIC.
S2MPG11 has 12 buck, 1 buck-boost, and 15 LDO rails. Several of these
can either be controlled via software (register writes) or via external
signals, in particular by:
* one out of several input pins connected to a main processor's:
* GPIO pins
* other pins that are e.g. firmware- or power-domain-controlled
without explicit driver intervention
* a combination of input pins and register writes.
Control via input pins allows PMIC rails to be controlled by firmware,
e.g. during standby/suspend, or as part of power domain handling where
otherwise that would not be possible. Additionally toggling a pin is
faster than register writes, and it also allows the PMIC to ensure that
any necessary timing requirements between rails are respected
automatically if multiple rails are to be enabled or disabled quasi
simultaneously.
While external control via input pins appears to exist on other
versions of this PMIC, there is more flexibility in this version, in
particular there is a selection of input pins to choose from for each
rail (which must therefore be configured accordingly if in use),
whereas other versions don't have this flexibility.
Add documentation related to the regulator (buck & ldo) parts like
devicetree definitions, regulator naming patterns, and additional
properties.
Since S2MPG11 is typically used as the sub-PMIC together with an
S2MPG10 as the main-PMIC, the datasheet and the binding both suffix the
rails with an 's'.

Note: checkpatch suggests to update MAINTAINERS, but the new file is
covered already due to using a wildcard.
v4:
- Krzysztof:
- move additionalProperties to after allOf
- use $defs, not definitions
- update samsung,ext-control: description
v3:
- mention NTC thermistor inputs in commit message
- drop PCTRLSEL values that can be described using standard properties
(Krzysztof), drop useless ones, rename the remaining ones
- drop maxItems:1 where not needed (Krzysztof)
- samsung,ext-control-gpios -> enable-gpios (Krzysztof)
- drop buckboost from 'allOf' limitation - not needed as it has its own
specific description
v2:
- fix commit message typos: s2mp1 -> s2mpg1
- mention GPIOs in commit message

The samsung,s2mpg10-pmic binding is going to acquire various additional
properties. To avoid making the common samsung,s2mps11 binding file too
complicated due to additional nesting, split s2mpg10 out into its own
file.
As a side-effect, the oneOf for the interrupts is not required anymore,
as the required: node is at the top-level now.

Update the regulators node to link to the correct and expected
samsung,s2mpg10-regulators binding, in order to describe the regulators
available on this PMIC.
Additionally, describe the supply inputs of the regulator rails, with
the supply names matching the datasheet.
While at it, update the description and example slightly.
Note: S2MPG10 is typically used as the main-PMIC together with an
S2MPG11 PMIC in a main/sub configuration, hence the datasheet and the
binding both suffix the supplies with an 'm'.

The Samsung S2MPG11 PMIC is similar to the existing S2MPG10 PMIC
supported by this binding, but still differs enough from it to justify
a separate binding.
It is a Power Management IC for mobile applications with buck
converters, various LDOs, power meters, NTC thermistor inputs, and
additional GPIO interfaces and typically complements an S2MPG10 PMIC in
a main/sub configuration as the sub-PMIC.
Like S2MPG10, communication is via the Samsung ACPM firmware and it
therefore needs to be a child of the ACPM firmware node.
Add the PMIC, the regulators node, and the supply inputs of the
regulator rails, with the supply names matching the datasheet.
Note: S2MPG11 is typically used as the sub-PMIC together with an
S2MPG10 PMIC in a main/sub configuration, hence the datasheet and the
binding both suffix the supplies with an 's'.

In a typical system using the Samsung S2MPG10 PMIC, an S2MPG11 is used
as a sub-PMIC.
The interface for both is the ACPM firmware protocol, so update the
binding to allow the relevant node and update the example here to
describe the connection for both PMICs.
Since we have two PMICs here, but can not use the 'reg' property (as
the addressing is based on software, i.e. the ACPM firmware), the node
names reflect that with their respective suffix. The existing 'pmic'
therefore becomes deprecated in favour of 'pmic-1'.
While at it, update the example.

Bucks can reasonably be supplies for LDOs, but not the other way
around. Since rail registration is going to be ordered by 'enum
s2mpg10_regulators', it makes sense to specify bucks first, so that
during LDO registration it is more likely that the corresponding supply
is known already.
This can improve probe speed, as no unnecessary deferrals and retries
are required anymore.

Add support for Samsung's S2MPG11 PMIC, which is a Power Management IC
for mobile applications with buck converters, various LDOs, power
meters, NTC thermistor inputs, and additional GPIO interfaces. It
typically complements an S2MPG10 PMIC in a main/sub configuration as
the sub-PMIC.
Like S2MPG10, communication is not via I2C, but via the Samsung ACPM
firmware.
While at it, we can also switch to asynchronous probe, which helps with
probe performance, as the drivers for s2mpg10 and s2mpg11 can probe in
parallel.
Note: The firmware uses the ACPM channel ID and the Speedy channel ID
to select the PMIC address. Since these are firmware properties, they
can not be retrieved from DT, but instead are deducted from the
compatible for now.

Note: checkpatch suggests to update MAINTAINERS, but the new file is
covered already due to using a wildcard.
v5:
- rebase
- one MFD cell per PMIC, not per PMIC rail (Mark)
- enable PROBE_PREFER_ASYNCHRONOUS
v4:
- rebase against next-20251121
v3:
- mention NTC thermistor inputs in commit message
- one instance per actual rail, not per rail type (LDO or buck)
v2:
- mention GPIOs in commit message

REGULATOR_LINEAR_VRANGE is similar to REGULATOR_LINEAR_RANGE, but
allows a more natural declaration of a voltage range for a regulator,
in that it expects the minimum and maximum values as voltages rather
than as selectors.
Using voltages arguably makes this macro easier to use by drivers and
code using it can become easier to read compared to
REGULATOR_LINEAR_RANGE.

While this commit doesn't introduce any users, the upcoming s2mpg10 and
s2mpg11 drivers are using it.

The initialisations being removed are needless, as both variables are
being assigned values unconditionally further down. Additionally, doing
this eager init here might lead to preventing the compiler from issuing
a warning if a future code change actually forgets to assign a useful
value in some code path.

dev_err_probe() exists to simplify code and harmonise error messages,
there's no reason not to use it here.
While at it, harmonise some error messages to add regulator name and ID
like in other messages in this driver, and update messages to be more
similar to other child-drivers of this PMIC (e.g. RTC).

André Draszik
For the upcoming S2MPG10 and S2MPG11 support, we need to be able to
parse -supply properties in the PMIC's DT node.
This currently doesn't work, because the code here currently points the
regulator core at each individual regulator sub-node, and therefore the
regulator core is unable to find the -supply properties.
Update the code to simply let the regulator core handle all the parsing
by adding the ::of_match and ::regulators_node members to all existing
regulator descriptions, by adding ::of_parse_cb() to those
regulators which support the vendor-specific samsung,ext-control-gpios
to parse it (S2MPS14), and by dropping the explicit call to
of_regulator_match().
Configuring the PMIC to respect the external control GPIOs via
s2mps14_pmic_enable_ext_control() is left outside ::of_parse_cb()
because the regulator core ignores errors other than -EPROBE_DEFER from
that callback, while the code currently fails probe on register write
errors and I believe it should stay that way.
The driver can now avoid the devm_gpiod_unhinge() dance due to
simpler error handling of GPIO descriptor acquisition.
This change also has the advantage of reducing runtime memory
consumption by quite a bit as the driver doesn't need to allocate a
'struct of_regulator_match' and a 'struct gpio_desc *' for each
regulator for all PMICs as the regulator core does that. This saves
40+8 bytes on arm64 for each individual regulator on all supported
PMICs (even on non-S2MPS14 due to currently unnecessarily allocating
the extra memory unconditionally). With the upcoming S2MPG10 and
S2MPG11 support, this amounts to 1640+328 and 1120+224 bytes
respectively.

Refactor s2mps14_pmic_enable_ext_control() and s2mps11_of_parse_cb()
slightly as a preparation for adding S2MPG10 and S2MPG11 support, as
both of those PMICs also support control of rails via GPIOs.
This also includes the following to avoid further updates in follow-up
commits:
* On S2MPG10 and S2MPG11, external rail control can be via GPIO or via
non-GPIO signals, hence passing a GPIO is allowed to be optional.
This avoids inappropriate verbose driver messages.
* Prepare to allow use of standard DT property name 'enable-gpios' for
newer platforms instead of vendor-specific 'samsung,ext-control'.

The S2MPG10 PMIC is a Power Management IC for mobile applications with
buck converters, various LDOs, power meters, RTC, clock outputs, and
additional GPIO interfaces.
It has 10 buck and 31 LDO rails. Several of these can either be
controlled via software (register writes) or via external signals, in
particular by:
* one out of several input pins connected to a main processor's:
* GPIO pins
* other pins that are e.g. firmware- or power-domain-controlled
without explicit driver intervention
* a combination of input pins and register writes.
Control via input pins allows PMIC rails to be controlled by firmware,
e.g. during standby/suspend, or as part of power domain handling where
otherwise that would not be possible. Additionally toggling a pin is
faster than register writes, and it also allows the PMIC to ensure that
any necessary timing requirements between rails are respected
automatically if multiple rails are to be enabled or disabled quasi
simultaneously.
This commit implements support for all these rails and control
combinations.
Additional data needs to be stored for each regulator, e.g. the input
pin for external control, or a rail-specific ramp-rate for when
enabling a buck-rail. Therefore, probe() is updated slightly to make
that possible.
Note1: For an externally controlled rail, the regulator_ops provide an
empty ::enable() and no ::disable() implementations, even though Linux
can not enable the rail and one might think ::enable could be NULL.
Without ops->enable(), the regulator core will assume enabling such a
rail failed, though, and in turn never add a reference to its parent
(supplier) rail. Once a different (Linux-controlled) sibling (consumer)
rail on that same parent rail gets disabled, the parent gets disabled
(cutting power to the externally controlled rail although it should
stay on), and the system will misbehave.
Note2: While external control via input pins appears to exist on other
versions of this PMIC, there is more flexibility in this version, in
particular there is a selection of input pins to choose from for each
rail (which must therefore be configured accordingly if in use),
whereas other versions don't have this flexibility.

v5:
- one instance per PMIC, not per rail or rail type (Mark)
v3:
- one instance per actual rail, not per rail type (LDO or buck)
- use REGULATOR_LINEAR_VRANGE macro
- sort s2mpg10 bucks before LDOs throughout (alphabetic ordering)
- LDO 1 and 7 also support setting a ramp rate
- add ::enable() to ops for signal-controlled rails and update commit
message detailing why
- more details around signal controlled rails in commit message
- switch to 'enable-gpios' instead of samsung,ext-control-gpios for
OS-controlled GPIOs (Krzysztof)
v2:
- move assignment of ::of_parse_cb in regulator_desc_s2mpg10_buck() to
match order of struct definition

The upcoming S2MPG11 support needs a similar, but different version of
::set_voltage_time(). For S2MPG10, the downwards and upwards ramps for
a rail are at different offsets at the same bit positions, while for
S2MPG11 the ramps are at the same offset at different bit positions.
Refactor the existing version slightly to allow reuse.

Rails in the S2MPG11 share a very similar set of properties with
S2MPG10 with slight differences. Update the existing macros to allow
reuse by the upcoming S2MPG11 driver.
Signed-off-by: André Draszik <andre.draszik@linaro.org>

Note: checkpatch complains about unused macro arguments _r_mask,
_r_table, and _r_table_sz, but these are false-positives due to patch
context.
v2:
- fix commit message typos: s2mp1 -> s2mpg1
- drop duplicated assignment of ::of_parse_cb in
regulator_desc_s2mpg1x_buck_cmn() macro

The S2MPG11 PMIC is a Power Management IC for mobile applications with
buck converters, various LDOs, power meters, and additional GPIO
interfaces. It typically complements an S2MPG10 PMIC in a main/sub
configuration as the sub-PMIC.
It has 12 buck, 1 buck-boost, and 15 LDO rails. Several of these can
either be controlled via software (register writes) or via external
signals, in particular by:
* input pins connected to a main processor's:
* GPIO pins
* other pins that are e.g. firmware- or power-domain-controlled
without explicit driver intervention
* a combination of input pins and register writes.
Control via input pins allows PMIC rails to be controlled by firmware,
e.g. during standby/suspend or as part of power domain handling where
otherwise that would not be possible. Additionally toggling a pin is
faster than register writes, and it also allows the PMIC to ensure that
any necessary timing requirements between rails are respected
automatically if multiple rails are to be enabled or disabled quasi
simultaneously.
This commit implements support for all these rails and control
combination.
Note1: For an externally controlled rail, the regulator_ops provide an
empty ::enable() and no ::disable() implementations, even though Linux
can not enable the rail and one might think ::enable could be NULL.
Without ops->enable(), the regulator core will assume enabling such a
rail failed, though, and in turn never add a reference to its parent
(supplier) rail. Once a different (Linux-controlled) sibling (consumer)
rail on that same parent rail gets disabled, the parent gets disabled
(cutting power to the externally controlled rail although it should
stay on), and the system will misbehave.
Note2: While external control via input pins appears to exist on other
versions of this PMIC, there is more flexibility in this version, in
particular there is a selection of input pins to choose from for each
rail (which must therefore be configured accordingly if in use),
whereas other versions don't have this flexibility.

v5:
- typos S2MPG10_LDOxx -> S2MPG11_LDOxx in s2mpg10_of_parse_cb()
- one instance per PMIC, not per rail or rail type (Mark)
v3:
- one instance per actual rail, not per rail type (LDO or buck)
- assign correct ::ops for LDOs with ramp support
- sort s2mpg11 bucks before LDOs throughout (alphabetic ordering)
- add ::enable() to ops for signal-controlled rails and update commit
message detailing why
- more details around signal controlled rails in commit message
v2:
- fix commit message typo
- mention GPIOs in commit message

Currently, GPIOs claimed by this driver for external rail control
all show up with "s2mps11-regulator" as consumer, which is not
very informative.
Switch to using the regulator name via desc->name instead, using the
device name as fallback.

Thanks for queuing these, but FYI, I think leaving out patches 1 to 3 will
give validation errors.
As mentioned in cover letter, the patches must be applied in order, for
bindings particularly the mfd-binding patches depend on the regulator-
binding updates, specifically patches 4 and 5 reference files added in
patches 2 and 3 respectively.
Also, without patch 1, I'd say there will be validation errors from the
example DTS that patch 1 updates in preparation for patch 4.
Maybe that's all OK while things are being merged via different trees, but
I just wanted to point it out.
Cheers,
Andre'

So long as everything lands in the final release it'll be fine, people
aren't bisecting DT binding validation in the way that they do runtime
issues.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
Thanks,
Mark
