      USB: remove optional bus bindings in isp1760, fixing runtime warning · ff30bf1c
      由 Sebastian Andrzej Siewior 提交于 
      Roland Reported the following:

The reason, is that ret is initialized with ENODEV instead of 0 _or_
the kmem cache is not freed in error case with no bus binding.

The difference between OF+PCI and OF only is

| 13748     676       8   14432    3860 isp1760-of.o

about 1.5 KiB.

Until there is a checkbox where the user *must* select atleast one item,
and may select multiple entries I don't make it selectable anymore.
Having a driver which can't be used under any circumstances is broken
anyway and I've seen distros shipping it that way.

      USB: fix ssb_ohci_probe() build bug · b22817b3
      由 Ingo Molnar 提交于 
      fix ssb_ohci_probe() build bug:

 drivers/built-in.o: In function `ssb_ohci_probe':
 ohci-hcd.c:(.text+0xbff39): undefined reference to `ssb_device_enable'
 ohci-hcd.c:(.text+0xbff6f): undefined reference to `ssb_admatch_base'
 ohci-hcd.c:(.text+0xbff8b): undefined reference to `ssb_admatch_size'
 ohci-hcd.c:(.text+0xbffe5): undefined reference to `ssb_device_disable'
 [...]

the reason was that this Kconfig combination was allowed:

 CONFIG_SSB=m
 CONFIG_USB_OHCI_HCD=y
 CONFIG_USB_OHCI_HCD_SSB=y

the fix is to require a modular USB_OHCI_HCD build when SSB is modular.

      USB: ehci_fsl update for MPC831x support · ba02978a
      由 Li Yang 提交于 
      For MPC831x support, change the ehci-fsl driver to preserve
bits set in platform code.  Add a common CONFIG_USB_EHCI_FSL
to indicate presence of Freescale EHCI SOC.  Add FSL_USB2_DR_OTG
operating mode support, thus both host and device can work for the
mini-ab receptacle.  Note: this doesn't enable OTG protocol
support.

      USB: r8a66597-hcd: host controller driver for R8A66597 · 5d304358
      由 Yoshihiro Shimoda 提交于 
      I would like to submit Renesas R8A66597 USB HCD driver.

R8A66597 is Renesas USB 2.0 host and peripheral combined
controller device originally designed for embedded products.
As a limitation of this device, it does not support externel
hub more than 2 tier, and cannot communicate with a USB
device more than 10. Then this device is not compatible with
EHCI and/or OHCI, I wrote driver support patch based on
sl811 code.

This driver has the following unique specifications:
- Implement transfer timeout to share one pipe with plural endpoint.
- Detach detection of a USB device connected to externel hub.

The driver has been tested external hub, usb-hdd, usb-cdrom,
usb-speaker, mice, keyboard, and usbtest driver.

      USB: EHCI support for big-endian descriptors · 6dbd682b
      由 Stefan Roese 提交于 
      This patch implements supports for EHCI controllers whose in-memory
data structures are represented in big-endian format. This is needed
(unfortunately) for the AMCC PPC440EPx SoC EHCI controller; the EHCI
spec doesn't specify little-endian format, although that's what most
other implementations use.

The guts of the patch are to introduce the hc32 type and change all
references from le32 to hc32.  All access routines are converted from
cpu_to_le32(...) to cpu_to_hc32(ehci, ...) and similar for the other
"direction".  (This is the same approach used with OHCI.)

David fixed:
	Whitespace fixes; refresh against ehci cpufreq patch; move glue
	for that PPC driver to the patch adding it; fix free symbol
	capture bugs in modified "constant" macros; and make "hc32" etc
	be "le32" unless we really need the BE options, so "sparse" can
	do some real good.

      USB: u132-hcd: host controller driver for ELAN U132 adapter · d774efea
      由 Tony Olech 提交于 
      This "u132-hcd" module is one half of the "driver" for
ELAN's U132 which is a USB to CardBus OHCI controller
adapter. This module needs the "ftdi-elan" module in
order to communicate to CardBus OHCI controller inserted
into the U132 adapter.

When the "ftdi-elan" module detects a supported CardBus
OHCI controller in the U132 adapter it loads this "u132-hcd"
module.

Upon a successful device probe() the single workqueue
is started up which does all the processing of commands
from the USB core that implement the host controller.

The workqueue maintains the urb queues and issues commands
via the functions exported by the "ftdi-elan" module. Each
such command will result in a callback.

Note that the "ftdi-elan" module is a USB client driver.

Note that this "u132-hcd" module is a (cut-down OHCI)
host controller.

Thus we have a topology with the parent of a host controller
being a USB client! This really stresses the USB subsystem
semaphore/mutex handling in the module removal.

      [PATCH] improved TT scheduling for EHCI · ba47f66b
      由 Dan Streetman 提交于 
      This updates the EHCI driver by adding an improved scheduler for the
transaction translators, found in USB 2.0 hubs and used for low and
full speed devices.

 - adds periodic_tt_usecs() and some helper functions, which does
   the same thing that "periodic_usecs" does, except on the other
   side of the TT, i.e.  it calculates the low/fullspeed bandwidth
   usage instead of highspeed.

 - adds a tt_available() function which is the new implementation
   of what tt_no_collision() does ... while tt_no_collision() ensures
   that each TT handles only 1 periodic transfer at a time (a very
   pessimistic approach) this version instead tracks bandwidth and
   allows each TT to handle as many transfers as will fit on each TT's
   downstream bus (closer to best-case).

The new scheduler is selected by a config option, marked as EXPERIMENTAL
so it can be tested (and more broadly reviewed) for a while until it
seems safe to remove the original scheduler.
