Thanks for the testing and dependency information.

I see that the PCI dependency has been accepted by Bjorn Helgaas.
And the phy dependency is both trivial and has been acked by Rob Herring
so it seems very likely to be accepted.

On the strength of the above I have accepted this series for v4.15.
