We are having more and more schema files.
Commit 8b6b80218b ("dt-bindings: Fix command line length limit
calling dt-mk-schema") fixed the 'Argument list too long' error of
the schema checks, but the same error happens while cleaning too.
'make clean' after 'make dt_binding_check' fails as follows:
$ make dt_binding_check
[ snip ]
$ make clean
make[2]: execvp: /bin/sh: Argument list too long
make[2]: *** [scripts/Makefile.clean:52: __clean] Error 127
make[1]: *** [scripts/Makefile.clean:66: Documentation/devicetree/bindings] Error 2
make: *** [Makefile:1763: _clean_Documentation] Error 2
'make dt_binding_check' generates so many .example.dts, .dt.yaml files,
which are passed to the 'rm' command when you run 'make clean'.
I added a small hack to use the 'find' command to clean up most of the
build artifacts before they are processed by scripts/Makefile.clean
