Resending it, since subject lines of earlier v2 patches missed the file 
sequence like PATCH 0/1 and 1/1.

This patch is created and tested on top of mainline linux 
commit d012a7190fc1 ("Linux 5.9-rc2")

Reference log of "make dt_binding_check" is available here[1].

I was able to reproduce the error after excluding the DT_SCHEMA_FILES
option. Just in case required the failure log is here[2].
