Some USB ports only have one possiblitly for the phy_type and
the type is not specified in the devicetree in this case.
Rely on the reset default instead of failing.

The old output of "help" was just producing a long list, that usually
scrolled of the screen (even on a X11 terminal). This list is more
compact, and also sorted by groups.
The old output format (plus grouping) is now available with 'help -v'.
Example:
Information commands:
?, devinfo, help, iomem, meminfo, version
Boot commands:
boot, bootm, go, loadb, loads, loadx, loady, saves, uimage
...

Subject: [PATCH] Fix AT91 UDC driver on boards without vbus.
While porting Barebox to one of our boards, we found that the AT91 UDC driver
will fail to connect to USB hosts, and will spam the console with errors if
the VBUS pin isn't connected.

This most likely doesn't fix any real bugs, but it's the

The fsl gadget driver wants to configure the portsc register
with information from platform_data. When registered from the
chipidea driver there is no platform_data. Fix the resulting
crash by not derefencing platform_data when NULL. In this
case the PORTSC register is not touched, it will have been
configured by the chipidea driver in this case.

Probe ULPI phys during USB initialization and not during driver

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.

This renames the USB devices to reflect the bus structure.
The base name for a USB device is usb<devno>. For each child
device we add a -<parent-port-no>. This makes it more easy
