Good to have DT patches early in a series but please order those in the same order as you then make use of them later in the series. In this case the continued discussion on patch 9 means I can't pick up patches 2/3 as they won't have a user yet. That blocks me picking up this and the GPIO controller support for now as well despite I think those being ready to go.
