make dtbs_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/file/to/test

It will check only the schema specified and check all the DT files
against only that schema (plus any referenced schema if you use a
top-level 'allOf'. See the GIC schema patch[2] for an example of
that).

I'm running the schema check for patches in the DT patchwork instance.
For example, here's this patch[1]. So as long as it has my R-by, then
it should be good. I'm not yet running the schema check on DT files
because generally there are warnings and I don't intend to fix them
for everyone. But maybe I should anyways so we at least have the data.

Ok. I'll apply this patch to clk-next with my small fixes rolled in.
