Don't you have any phy for this USB3 port?

Not as far as I can see. Why would I need one? The serdes signals are
connected directly to the mini-PCIe, just like the USB Type-A connector
on the same board. I haven't tested the USB3 signals on the mini-PCIe,
though, as I have no USB3 mini-PCIe device.

Right! I focused on the commit itself and missed the fact that it was
part of a PCI connector as stated in the title. I asked this because
usually we have a phy connected to a vcc signal.

Applied on mvebu/dt64

Thanks,

Gregory
