So I could not reproduce those issues either, it works for me fine on my
Pine-H64. I'd suggest we merge those patches, and check for more
reports from more users.

Bin, Marek: can you push patches 1, 2 and 3 to the USB tree, to get
them into the current merge window, still? I would then push 4/4
(pending possible fixes) once the first three reached mainline.

And btw: the first two patches of the original v1 series (adding the
sunxi clocks and reset bits) have been merged into master last week
already.

Thanks,
Andre
