[PATCH v4 1/2] dt-bindings: power: reset: qcom-pon: Add new compatible PMM8654AU

[Rakesh Kota]

PMM8654AU is a different PMIC from PMM8650AU, even though both share
the same PMIC subtype. Add PON compatible string for PMM8654AU PMIC
variant.

The PMM8654AU PON block is compatible with the PMK8350 PON
implementation, but PMM8654AU also implements additional PON registers
beyond the baseline. Use the PMM8654AU naming to match the compatible
string already present in the upstream pinctrl-spmi-gpio driver, keeping
device tree and kernel driver naming consistent.

My bot found errors running 'make dt_binding_check' on your patch:

yamllint warnings/errors:

See https://patchwork.kernel.org/project/devicetree/patch/20260323-b4-add_pwrkey_and_resin-v4-1-abef4e4dcc3d@oss.qualcomm.com

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

I don't understand this. The existing if/then schema did the exact same 
thing until you removed 'contains'. Now we just have the same schema 
duplicated.

What does need changing now that I've looked at it is dropping 'reg' 
in this schema as it just repeats what the top-level schema has.

But I did not suggest to add the contents in new if:then: block. I
certainly did not suggest to not check this patch before submitting, either.

We had long discussion where I asked you how many address spaces you
have there?

Answer above.

And then answer why the patch says the device has one address space or
two address spaces. You engaged me, Konrad and now Rob in reviewing this
triviality. This is on the verge of wasting of our time.

Krzysztof
