This is not a comment against _this_ patch. It was a question for Sean
Paul. You can tell this by the contents of the To: and Cc: headers on
Sascha's email. If that's not what was intended, then the email headers
are misleading.

The bindings are not part of this patch. This patch doesn't even care
about DT one bit - that's part of the design goal of it. It doesn't
care about platform devices either.
All it cares about is maintaining lists of struct device pointers,
asking the master device(s) whether they have all their components, and
binding/unbinding the components at the appropriate moment. It's
completely up to the master device operations to decide how to make
these decisions, and how those decisions are made, whether it be by
looking up in DT, or ACPI, or whatever.

in database were 13.1 to 19Mbit for a good line, about 7.5+ for a bad.
