US_BULK_FLAG_IN is defined as 1 and not used. The USB storage spec says
that bit 7 of flags within CBW defines the data direction. 1 is DATA-IN
(read from device) and 0 is the DATA-OUT. Bit 6 is obselete and bits 0-5
are reserved.
This patch redefines the unsued define US_BULK_FLAG_IN from 1 to 1 << 7
aka 0x80 and replaces the obvious users. In a following patch the
storage gadget will use it as well.

include/linux/usb/storage.h
This moves the BOT data structures for CBW and CSW from drivers internal
header file to global include able file in include/.
The storage gadget is using the same name for CSW but a different for
CBW so I fix it up properly. The same goes for the ub driver and keucr
driver in staging.

Fix checking of CTRL_PHY_CLK_VALID bit break on some platform on which
there is not USB CTRL_PHY_CLK_VALID bit.
- P1023/P3041/P5020 etc,have this bit
- P3060/4080/PSC913x do have this bit, but not mentioned in RM.
- P1022(perhaps and other) has no this bit

Shows up on ia64 builds (and possibly elsewhere) for configs that
don't set PM_RUNTIME or PM_SLEEP as follows:
drivers/usb/core/hcd-pci.c:383:12: warning: 'suspend_common' defined but not used
drivers/usb/core/hcd-pci.c:438:12: warning: 'resume_common' defined but not used
As per above, the functions are only used if RUNTIME/SLEEP are set,
so make the two functions conditional on these Kconfig values.

those routines have everything we need to map/unmap
USB requests and it's better to use them.
In order to achieve that, we had to add a simple
change on how we allocate and use our setup buffer;
we cannot allocate it from coherent anymore otherwise
the generic map/unmap routines won't be able to easily
know that the GetStatus request already has a DMA
address.

This changes the otg functions so that they receive struct

__do_config_autodelink passes the data variable to the transport function.
If the calling functions pass a stack variable, this will eventually trigger
a DMA-API debug backtrace for mapping stack memory in the DMA buffer. Fix
this by calling kmemdup for the passed data instead.

When build i.mx platform with imx_v6_v7_defconfig, and after adding
USB Gadget support, it has below build error:
CC drivers/usb/host/fsl-mph-dr-of.o
drivers/usb/host/fsl-mph-dr-of.c: In function 'fsl_usb2_device_register':
drivers/usb/host/fsl-mph-dr-of.c:97: error: 'struct pdev_archdata'
has no member named 'dma_mask'
It has discussed at: http://www.spinics.net/lists/linux-usb/msg57302.html
For PowerPC, there is dma_mask at struct pdev_archdata, but there is
no dma_mask at struct pdev_archdata for ARM. The pdev_archdata is
related to specific platform, it should NOT be accessed by
cross platform drivers, like USB.
The code for pdev_archdata should be useless, as for PowerPC,
it has already gotten the value for pdev->dev.dma_mask at function
arch_setup_pdev_archdata of arch/powerpc/kernel/setup-common.c.

We had a user report that running setserial on /dev/ttyACM0 didn't work.
He pointed at an old patch by Oliver Neukum from 2008 that never went anywhere..
http://permalink.gmane.org/gmane.linux.usb.general/9236
I made some minor changes to get it to apply again, and got the user to retest on 3.1,
and he reported it worked for him. https://bugzilla.redhat.com/show_bug.cgi?id=787607
The diff below is against 3.3rc. The only difference between this and
the version the user tested is the removal of the if (!ACM_READY) test
Havard removed ACM_READY in 99823f457d5994b3bd3775515578c8bfacc64b04
I'm unclear if there's need for a different test in its place.

We must not allow the input buffer length to change while we're
shuffling the buffer contents. We also mustn't clear the WDM_READ
flag after more data might have arrived. Therefore move both of these
into the spinlocked region at the bottom of wdm_read().
When reading desc->length without holding the iuspin lock, use
ACCESS_ONCE() to ensure the compiler doesn't re-read it with
inconsistent results.

Gobi 1000 devices have a different port layout, which wasn't respected
by the current driver, and thus it grabbed the QMI/net port. In the
near future we'll be attaching another driver to the QMI/net port for
these devices (cdc-wdm and qmi_wwan) so make sure the qcserial driver
doesn't claim them. This patch also prevents qcserial from binding to
interfaces 0 and 1 on 1K devices because those interfaces do not
respond.
