[PATCH 1/4] usb: ehci: Fixup efika hack for devicetree

[Sascha Hauer]

We used to distinguish which USB port to fixup by pdev->id. This
is < 0 for devicetree probed devices all the time, so this won't
work anymore once we switch to devicetree. Do the fixup on every
port instead, it doesn't hurt.

[PATCH 2/4] usb: i.MX chipidea: probe ULPI phys later

[Sascha Hauer]

Probe ULPI phys during USB initialization and not during driver
probe. This lowers the pressure to have the necessary board specific
setup in place early.
