My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):

yamllint warnings/errors:

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20221201225703.6507-2-ddrokosov@sberdevices.ru

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.

Why? This patch here is broken and it should be fixed. Don't apply
broken patches...

Node names should be generic.

Use 4 spaces for example indentation.

Dmitry is ressurecting a series that is several years old and not his to
begin with.

He was unsure about take the code of somebody else.
To be fair, he even asked for advice on IRC about to proceed.

Dmitry, as you may have guessed, for next revision, please fix Jian Hu
original patches in place, not with fixup patches.

If your fixes are minor (not complete rewrite), please keep the original
author and add your SoB

Do we really need the "xtal_" prefix ?

Seems like the clock is the PLL, not the xtal

We never take intentionally wrong patches, e.g. code which does not even
compile, and immediately fix it in next patch.

Can you imagine adding such drivers? Which are broken in the commit they
are added?

So the patchset is old or abandoned, take ownership, add co-developed
etc. Just don't add known broken code.

Best regards,
Krzysztof

Thank you for the link, will change it in the next version.

Good point, I've fixed it in the my patches above. But as you mentioned
in the all changes, I have to squash them....

Okay, I've got your point. It's reasonable.
I will fix Jian Hu's patches (squash with mine) and mark all of them
with co-developed and SoB Jian Hu tags. Thank you for explanation.

This name was formed from specification registers description. Register
CLKTREE_SYS_OSCIN_CTRL has "gate en" field which calls "xtal ->
HIFIPLL", therefore if was transformed to xtal_hifipll name.

But I agree with you, that "hifipll" is better name choice.

It was clearly explained in the cover-letter, nobody expected these patches
to be applied as-is.

Using RFC would have been the best solution, but this situation is rather
specific and he made the right decisions to trigger this current discussion
toward an acceptable solution for everybody.
