You still keep developing it on wrong, old kernel (or not using
get_maintainers.pl, but this one seems too obvious so I assumed wrong
kernel).

Node names should be generic. See also an explanation and list of
examples (not exhaustive) in DT specification:

for sure "ti" is not generic. pvu is the device name.
