Subject: [PATCH 0/2] dt-bindings: Improve yamllint performance

	Hi Rob,

This series improves yamllint performance by parallelizing the
operation, and by restricting the checked files to those specified using
DT_SCHEMA_FILES.

Changes compared to v1:
  - New patch to parallelize yamllint,
  - Introduce find_all_cmd,
  - Only use the restricted set for yamllint.

I've been using this for the past 6 months, as it helps a lot when
writing or updating DT bindings.  Combined, this reduces the execution
time of

    make dt_binding_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/your/binding/file.yaml

from ca. 30 to 10 s on i7-8700K.

Thanks for your comments!

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
