Add support for testing single device tree file by running
'make tree.dt.yaml', e.g. 'make ARCH=arm64 qcom/qrb5165-rb5.dt.yaml'.
This looks useful for checking idividual changes to dts files.

typo

I'd rather not expose .*.dt.yaml as I want to make checking not
optional and I have some plans of integrating the schema checks into
dtc which would eliminate .dt.yaml files. Instead, I think %.dtb
targets should run the checks always.

I don't think we should expose this detail (processed-schema.json) to
the top-level makefile. This will be built if 'dt_binding_check' is a
dependency with CHECK_DTBS=y set.

CHECK_DTBS here doesn't work. It has to be exported.

So here's my modified patch (%.dtbo should probably be included too,
but I'm not yet sure how well the schema checks will work on them):

I do not understand how this will work.

'make foo.dtb' will also create foo.dt.yaml
(that is, schema check is always run) ?

Yes, that is my intent. As I mentioned above, I have some plans to
integrate the schema checks into dtc which would eliminate .dt.yaml
files. So I don't really want to add them as a user make target if we
might remove it. Also, at some point, running the schema checks
shouldn't be optional. We can't do that yet for 'dtbs' as there's a
bunch of warnings. But for %.dtb targets, I don't think getting the
warnings is a problem.

OK, your plan is to perform schema-check
as a side-effect of dtb compilation.

The current dt-schema tool only works against yaml files.
Once it is integrated into DTC, will it be able to directly handle .dts files?

Please excuse me for letting this float for some time. Do you plan to
submit your patch?
Would you like me to do it instead?
