From: Fabien Parent <[email protected]>
The verbose option '-B' will show additional messages in addition
to all validation errors. Right now the level 0 prints every nodes
which don't have at least one schema associated to it. Level 1
prints every properties which were not validated due to missing
constraints.
Activate the verbose mode by default into the Makefile.
Usage example:
dtc -M ./bindings -B 1 file.dts
A count of errors found so far as also been added and is printed
on each error.
