I notice that there are other two patches in the series that put the
configuration info under the mux node. ;-) They are with SoCs / boards
that I wasn't really involved in and so I won't do anything to block
them from landing but, as per my replies to v1 it's not my favorite...
In any case, this patch here looks great to me. Thanks! Looking
forward to seeing these converted over to the scheme that your sc7180
patches used.
