Okay, but what I am looking for is an explanation of why it is okay to
change the node from

| regulator@34 {
|   compatible = "infineon,ir38060";
|   reg = <0x34>;
| 
|   regulator-min-microvolt = <437500>;
|   regulator-max-microvolt = <1387500>;
| };

to

| regulator@34 {
|     compatible = "infineon,ir38060";
|     reg = <0x34>;
| 
|     regulators {
|         vout {
|             regulator-name = "p5v_aux";
|             regulator-min-microvolt = <437500>;
|             regulator-max-microvolt = <1387500>;
|         };
|     };

?

Will the driver handle both of these identically? Is backwards
compatibility with the old format maintained? Was the original format
wrong and does not work? Why is a list of regulators needed when the
device only provides one?

Cheers,
Conor.

As I have understood the driver, this isn't supported.

Above is the typical approach in other pmbus dt bindings.
Even pmbus driver expects this approach.

Driver doesn't support both.
Based on the pmbus driver original format was wrong.
pmbus driver looks for a regulator node to start with.

Then all of the in-tree users are all just broken? They're in aspeed
bmcs, so I would not be surprised at all if that were the case.
Can you send a new version with a fixes tag and an explanation that what
was there was wrong?

Sure. I will add an explanation in the commit message.
I'm not sure what you meant by 'fixes tag'

I am surprised you don't know what a fixes tag is, feel like you've been
around long enough to encounter one! They look like Fixes: <hash> ("<shortlog>")
and there should be documentation on them at https://docs.kernel.org/process/submitting-patches.html#describe-changes

Can you unpack the intent of this remark for me a little?

The history of the problem from what I can see looks like:

   1. pmbus regulator support exploiting "regulators" as an OF child
      node was merged for 3.19[1]
   2. The infineon driver support was merged with trivial bindings[2]
      and released in v5.17
   3. A patch was proposed that extracted the Infineon regulator
      compatibles and provided a dedicated binding[3], however it
      lacked the "regulators" object property 
   4. The patch in 3 was merged as [4] with relevant tags, and was
      released in v6.9
   5. The system1 devicetree was merged and released in v6.10, and sbp1
      is merged in v6.14-rc1 for release in v6.14. Both devicetrees, as
      far as I'm aware, conform to the binding as written.

In addition to keeping an eye out for Rob's bot, I check all Aspeed-
related devicetree patches against the bindings using the usual tooling
while applying them. I would like to avoid diving into driver
implementations as a blocker to applying devicetree patches where
possible - the formalised bindings and tooling should exist to separate
us from having to do that.

If the complaint is that people submitting Aspeed devicetree patches
are regularly not testing them to make sure they behave correctly on
hardware, then sure, that's something to complain about. Otherwise, I'm
well aware of the (Aspeed) bindings and warnings situation; we've
spoken about it previously. If there's something I should change in my
process (beyond eventually addressing all the warnings) please let me
know, but I don't see that there is in this specific instance.

I hope you mean "make full use of and derive benefit from (a resource)"
and not "use (a situation or person) in an unfair or selfish way".
If you think it is not appropriate for PMBus devices to register as
regulators, please let me know, and feel free to suggest a better solution.

Certainly "make full use of and derive benefit from (a
resource)" and nothing further.

My only intent was to observe the history of the problem highlighted by
Naresh's patch. I don't have any concerns about PMBus devices
registering as regulators.

Ye, it's not a jab at aspeed maintainership, it's about the bmc stuff in
particular. I saw far too many warnings from Rob's bot on series with a
version number where the submitter should know better, so the idea that
it had not been tested in other ways wasn't exactly a stretch.

I made a mistake how I pulled these devices out of trivial-devices.yaml,
given the existing driver didn't work with that binding, but I don't
really see why there's a requirement for a regulator child here in the
first place. I get it for something like the lm25066 that is a monitor
IC that you connect a regulator to, as the regulator is a distinct
device - but the ir38060 is a regulator that has a pmbus interface so
both describe the same device.

Makes sense. Maybe it's best to support the existing description in
pmbus core as Rob's already suggested in another part of the thread.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade

[PATCH 1/2] dt-bindings: hwmon: ir38060: Move & update dt binding

[Naresh Solanki]

Move dt binding under hwmon/pmbus & align accordingly.

Previously the DT binding was invalid & wouldn't work with pmbus driver.
Pmbus driver expects a regulator node & hence added the same.

2 out of 3 (schema, dts, driver) agree. Fix the driver.

Nothing new here, but WTF. Expect a meta-schema change to warn on this.
