Yes, but after drop export of_default_bus_match_table in patchset(15/15),
we will meet build issue, so the statement can be changed to
------------
After covering to use helper of_platform_default_populate() to
populate the default bus, this driver can be safely as a tristate
one, no error in build uniphier driver as a module once we drop
export of_default_bus_match_table in later patch.

a new one with update changlog, thanks for your review.
