[PATCH v1 2/3] drm/ci: Add jobs to validate devicetrees
Posted by Vignesh Raman 8 months, 3 weeks ago 
Add jobs to run dt_binding_check and dtbs_check. If warnings are seen,
exit with a non-zero error code while configuring them as warning in
the GitLab CI pipeline.

Can it really succeed or is it going to be an always-failing job? The
dt_binding_check generally succeed, dtbs_check generates tons of
warnings. We are trying to make progress there, but it's still very far
from being achevable.

You don't need to build dtbs separately, dtbs_check includes dtbs.

Even though it fails, it will be shown as a warning in the pipeline.

I think what Dmitry was pointing out is that a warning that is always
warning is going to be completely ignored, and thus doesn't add any
value.

It depends on the platforms I guess. Some are 100% covered and any
warning should be treated as a failure, and some have not started the
effort.

I guess we could solve it with some kind of expectation list, but I do
wonder if it's something *we* should be focusing on :)

I think that we might want to limit this to `make dt_bindings_check
DT_SCHEMA_FILES=display`, checking all GPU / display schema files.
