[PATCH 0/5] Add support for Ezurio MediaTek platforms

[Gary Bisson]

This series adds support for Ezurio MediaTek platforms called
"Tungsten". It includes support for MT8370-based Tungsten 510 and
MT8390-based Tungsten 700 SOMs.

Why only two of us? Please don't work on old kernels, some ancient code.

Please use scripts/get_maintainers.pl to get a list of necessary people
and lists to CC (and consider --no-git-fallback argument, so you will
not CC people just because they made one commit years ago). It might
happen, that command when run on an older kernel, gives you outdated
entries. Therefore please be sure you base your patches on recent Linux
kernel.

Tools like b4 or scripts/get_maintainer.pl provide you proper list of
people, so fix your workflow. Tools might also fail if you work on some
ancient tree (don't, instead use mainline) or work on fork of kernel
(don't, instead use mainline). Just use b4 and everything should be
fine, although remember about `b4 prep --auto-to-cc` if you added new
patches to the patchset.

Actually I'm using master so the get_maintainer.pl output is fine, just
wasn't using b4 and addding the CC myself, will resend with b4 and will
update the patches per your review.

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20251201084140.376058-2-bisson.gary@gmail.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.

This link gives me a 404 error, is it expected?

Couldn't reproduce, I can't seem to see any error/warning that would be
introduced by this patch, can the above be discarded then?

And here Conor? Just use b4.

Anyway, please squash this and 3/5, it's just churn if boards are
per-commit.

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

yamllint warnings/errors:

dtschema/dtc warnings/errors:


doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20251201084140.376058-3-bisson.gary@gmail.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.

Did you disable it anywhere?

Node names should be generic. See also an explanation and list of
examples (not exhaustive) in DT specification:
https://devicetree-specification.readthedocs.io/en/latest/chapter2-devicetree-basics.html#generic-names-recommendation
If you cannot find a name matching your device, please check in kernel
sources for similar cases or you can grow the spec (via pull request to
DT spec repo).

e.g. pmic

[PATCH 5/5] arm64: dts: mediatek: add device tree for Tungsten 700 board

[Gary Bisson]

Add device tree to support Ezurio Tungsten 700 (MT8390) SMARC SOM [1] +
Universal SMARC carrier board [2].
It includes support for the MIPI-DSI BD070LIC3 display which uses the
Tianma TM070JDHG30 panel + TI SN65DSI84 MIPI-DSI to LVDS bridge [3].
