We can argue whether 63xx came before 7xxx in terms of time line, but that still does not justify the rename IMHO. I realized that we are missing a 7038 pattern in the MAINTAINERS file for the BCM7XXX entry, and that will be fixed shortly after sending this email. Please add Justin Chen (original author) and myself as maintainers for this binding.
