Separate the Davinci OHCI host controller driver from ohci-hcd
host code so that it can be built as a separate driver module.
This work is part of enabling multi-platform kernels on ARM

[Axel: adapted and rebased,
Intel's BXT devices need to execute a _DSM method
during {runtime_,}{suspend,resume} in order to get a
chunk of dwc3 to power gate and save some extra
power.
Let's do that now.

In cases where we're given an SG-list which is
longer than the amount of currently available TRBs,
we will be left with the same request on
started_list and we should prioritize that request
over possible new requests on pending_list. That's
a way to guarantee requests complete in order.

When we get a half-way processed request, we should
make sure to try to prepare further TRBs for it or
for any possibly queued up request held in our
pending_list. This will make sure our controller is
kept busy for as long as possible.

This will give us a simpler way of figuring out how
many bytes were left in each TRB. It's useful for
cases where we queue only part of an SG-list due to
amount of available TRBs at the time of kicking the
transfer.

Say we have three requests prepared to the HW (reqA,
reqB, and reqC). All of them are composed of
SG-lists with several entries and they all requests
interrupt only on last TRBs of the SG-list.
When we get interrupt for reqA, it could be that
reqB is already half-way transferred and some of its

If XferNotReady comes before usb_ep_queue() we will
set our PENDING request flag and wait for a
request. However, originally, we were assuming
usb_ep_queue() would always happen before our first
XferNotReady and that causes a corner case where we
could try to issue ENDTRANSFER command before

This adds the device tree node for the usb otg

Hi Felipe,
That's some great information, thanks!
At first glance, the DSDT table has two interesting bits. (I would
paste the decompiled source, but I think it may be copyrighted?
Correct me if I'm wrong.) The first is the USB mux, an SMSC USB3750
connected to I2C1. According to the datasheet, t

In reading through a USB interface driver, I noticed that it called
usb_{get,put}_dev() in its probe() and disconnect() methods. This seemed
unnecessary, but a look at the comments here matched the usage.
USB interface devices seem to be well covered by the parent/child
relationship of the device
