Many newer Option mobile broadband devices initially provide a
usb-storage "driver CD" device that's pretty useless on Linux since
any software on it most likely wouldn't be compatible with your
kernel or distro anyway. Thus, by default just kill the driver
CD device by sending the SCSI 'rezero' command, but allow override
of the default behavior via usb-storage module parameter so users
can keep the ZeroCD device if they really want to. Inspired by
the Sierra TruInstall patch.Signed-off-by: Dan Williams

It is enough to protect accesses to reject field of urb
by marking it as atomic_t,also it is the only reason of
existence of usb_reject_lock,so remove the lock to make

This patch (as1185) makes usbcore take advantage of the bus
notifications sent out by the driver core. Now we can create all our
device and interface attribute files before the device or interface
uevent is broadcast.A side effect is that we no longer create the endpoint "pseudo"
devices at the same time as a device or interface is registered -- it
seems like a bad idea to try registering an endpoint before the
registration of its parent is complete. So the routines for creating
and removing endpoint devices have been split out and renamed, and
they are called explicitly when needed. A new bitflag is used for
keeping track of whether or not the interface's endpoint devices have
been created, since (just as with the interface attributes) they vary
with the altsetting and hence can be changed at random times.Signed-off-by: Alan Stern

The DPCM subdriver is a little peculiar, in that it's meant to support
devices where LUN 0 is Compact Flash and uses the CB transport whereas
LUN 1 is SmartMedia and uses the SDDR09 transport. Thus DPCM isn't
really a transport in itself; it's more like a demultiplexer.Much of the DPCM code is part of the SDDR09 subdriver already, and the
remaining part is fairly small. This patch (as1182) moves that extra
piece into sddr09.c, thereby eliminating dpcm.c. Also eliminated is
the Kconfig entry for DPCM support; it is now listed as part of the
SDDR09 entry.In order to make sure that the semantics are the same as before, each
unusual_devs entry for DPCM is now present twice: once with DPCM
support if SDDR09 is configured (as before), and once with the
SINGLE_LUN flag and CB support otherwise.Signed-off-by: Alan Stern

Contains fixes so probe on x86 PCI runs, apparently I'm first to try
this. Several fixes to memory access to probe host scratch register.
Previously would bug check on chip_addr var used uninitialized.
Scratch reg write failed in one instance due to 16-bit initial access
mode, so added "& 0x0000ffff" to the readl as fix.
Includes some general cleanup - remove global vars, organize memory map

This patch (as1177) modifies the USB core suspend and resume
routines. The resume functions now will take a pm_message_t argument,
so they will know what sort of resume is occurring. The new argument
is also passed to the port suspend/resume and bus suspend/resume
routines (although they don't use it for anything but debugging).In addition, special pm_message_t values are used for user-initiated,
device-initiated (i.e., remote wakeup), and automatic suspend/resume.
By testing these values, drivers can tell whether or not a particular
suspend was an autosuspend. Unfortunately, they can't do the same for
resumes -- not until the pm_message_t argument is also passed to the
drivers' resume methods. That will require a bigger change.IMO, the whole Power Management framework should have been set up this
way in the first place.Signed-off-by: Alan Stern

This patch (as1178) uses the new round_jiffies_up_relative() routine
for setting the autosuspend delayed_work timer. It's appropriate
since we don't care too much about the exact length of the delay, but
we don't want it to be too short (rounded down).Signed-off-by: Alan Stern

gpio_vbus provides simple GPIO VBUS sensing for peripheral
controllers with an internal transceiver.
Optionally, a second GPIO can be used to control D+ pullup.It also interfaces with the regulator framework to limit charging
currents when powered via USB. gpio_vbus requests the regulator
supplying "vbus_draw" and can enable/disable it or limit its
current depending on USB state.[dbrownell@users.sourceforge.net: use drivers/otg, cleanups ]

This moves the isp1301-omap driver from the drivers/i2c/chips
directory (which will be shrinking) into a new drivers/usb/otg
directory (which will grow, with more drivers and utilities).Note that OTG infrastructure needs to be initialized before
either host or peripheral side USB support, and may be needed
before for pure host or pure peripheral configurations.Signed-off-by: David Brownell

Random host-side MUSB updates, mostly relating to better diagnostics:
+ Improve diagnostics on host side:
- tx flush fifo:
* Avoid hundreds of duplicate TX FIFONOTEMPTY messages
* make "Can't flush TX fifo" a warning, and say which endpoint
- giveback:
* use correct status code
* show completion function name not just URB pointer
- Fix annoying "1 bytes" (should be "1 byte")+ Be more consistent about failing init of unusable fifo_mode
It's not clear why that "can't flush TX fifo" message appears, though
it might relate to disconnection; I see it not infrequentlySigned-off-by: David Brownell

This patch (as1175) makes usb-storage set a SCSI device's
request-queue bounce limit such that all buffers will be located in
addressable memory (i.e., not in high memory) if the host controller's
dma_mask is NULL. This is necessary when the host controller doesn't
support DMA: If a buffer is in high memory then the both the virtual
and DMA addresses produced by the scatter-gather library will be NULL,
preventing the HCD from accessing the buffer's data.In particular, the isp1760 driver needs this when used on a system
with more than 1 GB of memory.Signed-off-by: Alan Stern
