Merge tag 'gadget-for-v3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next
USB: Gadget: changes for 3.4
This merge is rather big. Here's what it contains:
For am5536udc we have just simple coding style fixes. Nothing that has any
potential to cause any issues going forward.
With mv_udc, there's only one single change removing an unneeded NULL check.
at91_udc also only saw a single change this merge window, and that's only
removing a duplicated header.
The Renesas controller has a few more involved changes. Support for SUDMAC was
added, there's now a special handling of IRQ resources for when the IRQ line is
shared between Renesas controller and SUDMAC, we also had a bug fix where
Renesas controller would sleep in atomic context while doing DMA transfers from
a tasklet. There were also a set of minor cleanups.
The FSL UDC also had a scheduling in atomic context bug fix, but that's all.
Thanks to Sebastian, the dummy_hcd now works better than ever with support for
scatterlists and streams. Sebastian also added SuperSpeed descriptors to the
serial gadgets.
The highlight on this merge is the addition of a generic API for mapping and
unmapping usb_requests. This will avoid code duplication on all UDC controllers
and also kills all the defines for DMA_ADDR_INVALID which UDC controllers
sprinkled around. A few of the UDC controllers were already converted to use
this new API.

USB: transceiver changes for 3.4
Here we have a big rework done by Heikki Krogerus (thanks) which
splits OTG functionality away from transceivers.
We have known for quite a long time that struct otg_transceiver was
a bad name for the structure, considering transceiver is far from
being OTG-specific (see 4e67185).
Merge tag 'musb-for-v3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next
USB: MUSB changes for 3.4
Here are a set of changes to the MUSB driver. In summary we have
a patch making modules behave better, there's a fix on debugfs'
error path, a small change removing an unnecessary pm_runtime
call on musb_shutdown() and a fix to relesect the endpoint in
Interrupt context.
This last patch is needed because we must drop musb's lock when
calling request->complete() and that could cause problems if another
thread queues a request and ends up changing MUSB_INDEX register.
To quote Shengzhou Liu:
I'm sorry, please don't apply this patch.
It appears not only on P1022 platform.
There will be more breaks on other platforms regarding
CTRL_PHY_CLK_VALID bit.
I will post a new patch with well compatibility on all
platforms as soon as I get necessary confirmations.
USB: serial: add Fintek F81232 usb to serial driver
This is the first cut at a driver for the Fintek F81232 USB to serial
single port converter. This provides the initial framework for the
device, and some data can move through it, but no line settings are
handled, so it's not that useful yet. It does give people a starting
place to work from.
Thank to Fintek for providing samples and specifications, without which,
this driver would have never been able to be written.

USB: create module_usb_serial_driver macro
Now that Alan Stern has cleaned up the usb serial driver registration,
we have the ability to create a module_usb_serial_driver macro to make
things a bit simpler, like the other *_driver macros created.
But, as we need two functions here, we can't reuse the existing
module_driver() macro, so we need to roll our own.
Here's a patch implementing module_usb_serial_driver() and it converts
the pl2303 driver to use it, showing a nice cleanup.
usb/storage: remove Filler member from struct bulk_cs_wrap
As Alan Stern pointed out this member has nothing to do with the Command
Status Wrapper (CSW) as specified by the Universal Serial Bus Mass
Storage Class Bulk-Only Transport rev 1.0. It defines the structure
without the additional 18 filler bytes and defines the total size of the
struct to exactly 13 bytes. Larger responses should be dropped. All
in-tree users use a defines instead of sizeof() of this struct as far I
can tell.

This patch redefines the unsued define US_BULK_FLAG_IN from 1 to 1 << 7

This ehci driver is mainly designed to support host controller found on
Marvell PXA and MMP Soc series.
Add the dependence to avoid the potential build failure which may
include two EHCI controller drivers.

USB: ums_realtek: do not use stack memory for DMA in __do_config_autodelink
__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.

usb: Fix build error due to dma_mask is not at pdev_archdata at ARM
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.

USB: allow users to run setserial with cdc-acm
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.

cdc-wdm: Fix more races on the read path
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.

USB: qcserial: don't grab QMI port on Gobi 1000 devices
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.
