The Synopsys USB device controller requires all OUT transfer request
lengths to be aligned to max packet size. The mass storage gadgets do
not meet this requirement for Super Speed. The gadgets already have a
function which performs this alignment for CBW packets, so use it for
data packets too.
The alternative would be to implement bounce buffers in the DWC3
driver, but that could have a significant impact on performance.
This version is based upon a more-correct patch written by Alan
Stern.

The code in the MIDI gadget was already sort of prepared for multi-port
configuration, so the streaming logic itself didn't need much tweaking.
However, the descriptors change when the number of ports do, and so some
rework of the the preparation algorithms were necessary.
Successfully tested on Linux and Max OS X hosts for both input and
output streams.

Make use of the newly added MIDI function in f_midi.c and strip down
the MIDI gadget code radically. Also use the generic framework function
to avoid code duplication and rename some symbols to bring them in sync
with other code in the gadget framework.

This patch adds f_midi.c to implement a USB gadget function that works
with the composite framework, so it can be combined with other USB
functions.
The code for the ALSA/MIDI logic was taken from the midi device gadget,
other parts have been rewritten to benefit from the dynamic descriptor
allocation features.
This was successfully tested on an OMAP3 board.

R8A66597 has the pin of WR0 and WR1. So, if one write-pin of CPU
connects to the pins, we have to change the setting of FIFOSEL
register in the controller. If we don't change the setting,
the controller cannot send the data of odd length.

An older version of the databook said to wait for the FIFO to
drain, but that has been removed from the newer databooks.
Waiting for RxFIFO to drain caused problems when testing against
one of the host controllers available in the market.
After talking to one of the RTL engineers, he stated that we
should _not_ wait for RxFIFO to drain.

According to USB 3.0 Specification, a SetAddress()
while device is in Configured State has an unspecified
behavior (see Section 9.4.6). Still USB30CV wasn't
happy with my Stall reply.
To make that thing happy, just accept the SetAddress()
always. No problems have been observed thus far.

Add to the dev_state and alloc_async structures the user namespace
corresponding to the uid and euid. Pass these to kill_pid_info_as_uid(),
which can then implement a proper, user-namespace-aware uid check.
Changelog:
Sep 20: Per Oleg's suggestion: Instead of caching and passing user namespace,
uid, and euid each separately, pass a struct cred.
Sep 26: Address Alan Stern's comments: don't define a struct cred at
usbdev_open(), and take and put a cred at async_completed() to
ensure it lasts for the duration of kill_pid_info_as_cred().

Alan Stern points out that after spin_unlock(&ps->lock) there is no

This patch (as1488) improves the comments and logic in uhci-hcd's
suspend routine. The existing comments are hard to understand and
don't give a good idea of what's really going on.
The question of whether EGSM (Enter Global Suspend Mode) and RD
(enable Resume Detect interrupts) can be useful when they're not both
set is difficult. The spec doesn't give any details on how they
interact with system wakeup, although clearly they are meant to be
used together. To be safe, the patch changes the subroutine so that
neither bit gets set unless they both do. There shouldn't be any
functional changes from this; only systems that are designed badly or
broken in some way need to avoid using those bits.

This patch (as1486) implements the kernel's new wakeup policy for USB
host controllers. Since they don't generate wakeup requests on their
but merely forward requests from their root hubs toward the CPU, they
should be enabled for wakeup by default.
Also, to be compliant with both the old and new policies, root hubs
should not be enabled for remote wakeup by default. Userspace must
enable it explicitly if it is desired.

This removes the need of ifdefs within the init function and with it the
headache about the correct clean without bus X but with bus/platform Y &
Z.
xhci-pci is only compiled if CONFIG_PCI is selected which can be
de-selected now without trouble. For now the result is kinda useless
because we have no other glue code. However, since nobody is using
USB_ARCH_HAS_XHCI then it should not be an issue :)

xhci_pci_setup() is split into three pieces:
- xhci_gen_setup()
The major remaining of xhci_pci_setup() is now containing the generic
part of the xhci setup. It allocates the xhci struct, setup
hcs_params? and friends, performs xhci_halt(), xhci_init and so one.
It also obtains the quirks via a callback
- xhci_pci_quirks()
It checks the origin of the xhci core and sets core specific quirks.
- xhci_pci_setup()
PCI specific setup functions. Besides calling xhci_gen_setup() with
xhci_pci_quirks() as an argument it performs PCI specific setup like
obtaining the address of sbrn via a PCI config space.
