5ce524bdff scsi/sd: add a no_read_capacity_16 scsi_device flag
I seem to have a knack for digging up buggy usb devices which don't work
with Linux, and I'm crazy enough to try to make them work.  So this time a
friend of mine asked me to get an mp4 player (an mp3 player which can play
videos on a small screen) to work with Linux.

It is based on the well known rockbox chipset for which we already have an
unusual devs entries to work around some of its bugs.  But this model
comes with an additional twist.

This model chokes on read_capacity_16 calls.  Now normally we don't make
those calls, but this model comes with an sdcard slot and when there is no
card in there (and shipped from the factory there is none), it reports a
size of 0.  However this time the programmers actually got the
read_capacity_10 response right!  So they substract one from the size as
stored internally in the mp3 player before reporting it back, resulting in
an answer of ...  0xffffffff sectors, causing sd.c to try a
read_capacity_16, on which the device crashes.

This patch adds a flag to scsi_device to indicate that a a device cannot
handle read_capacity_16, and when this flag is set if a device reports an
lba of 0xffffffff as answer to a read_capacity_10, assumes it tries to
report a size of 0.

ae38c78a03 usb-storage: add new no_read_disc_info quirk
Appotech ax3003 (the larger brother of the ax203) based devices are even
more buggy then the ax203.  They will go of into lala land when ever they
see a READ_DISC_INFO scsi command.  So add a new US_FL which tells the
scsi sr driver to not issue any READ_DISC_INFO scsi commands.

8e04d8056c scsi/sr: add no_read_disc_info scsi_device flag
Some USB devices emulate a usb-mass-storage attached (scsi) cdrom device,
usually this fake cdrom contains the windows software for the device.
While working on supporting Appotech ax3003 based photoframes, which do
this I discovered that they will go of into lala land when ever they see a
READ_DISC_INFO scsi command.

Thus this patch adds a scsi_device flag (which can then be set by the
usb-storage driver through an unsual-devs entry), to indicate this, and
makes the sr driver honor this flag.

I know this sucks, but as discussed on linux-scsi list there is no other
way to make this device work properly.

Looking at usb traces made under windows, windows never sends a
READ_DISC_INFO during normal interactions with a usb cdrom device.  So as
this cdrom emulation thingie becomes more common we might see more of this
problem.

319feaabb6 usb: gadget: goku_udc: Fix error path
This is based on an initial patch by Rahul Ruikar.

The goku_remove() function can be called before device_register() so it
can call device_unregister() improperly.  Also if the call to
device_register() fails we need to call put_device().

As I was changing the error handling in goku_probe(), I noticed that
the label was "done" but actually if the function succeeds we return
earlier.  I renamed the error path to "err" instead of "done."

d0cc3d4100 USB: imx21-hcd accept arbitary transfer buffer alignement.
The hardware can only do DMA to 4 byte aligned addresses.
When this requirement is not met use PIO or a bounce buffer.

PIO is used when the buffer is small enough to directly
use the hardware data memory (2*maxpacket).

A bounce buffer is used for larger transfers.

80f0cf3947 USB: disable endpoints after unbinding interfaces, not before
This patch (as1430) fixes a bug in usbcore.  When a device
configuration change occurs or a device is removed, the endpoints for
the old config should be completely disabled.  However it turns out
they aren't; this is because usb_unbind_interface() calls
usb_enable_interface() or usb_set_interface() to put interfaces back
in altsetting 0, which re-enables the interfaces' endpoints.

As a result, when a device goes through a config change or is
unconfigured, the ep_in[] and ep_out[] arrays may be left holding old
pointers to usb_host_endpoint structures.  If the device is
deauthorized these structures get freed, and the stale pointers cause
errors when the the device is eventually unplugged.

The solution is to disable the endpoints after unbinding the
interfaces instead of before.  This isn't as large a change as it
sounds, since usb_unbind_interface() disables all the interface's
endpoints anyway before calling the driver's disconnect routine,
unless the driver claims to support "soft" unbind.

This fixes Bugzilla #19192.  Thanks to "Tom" Lei Ming for diagnosing
the underlying cause of the problem.

f405387435 USB: MUSB: fix kernel WARNING/oops when unloading module in OTG mode
Since commit 461972d8a4 (musb_core: don't call
musb_platform_exit() twice), unloading the driver module results in a WARNING
"kobject: '(null)' (c73de788): is not initialized, yet kobject_put() is being
called." (or even kernel oops) on e.g. DaVincis, though only in the OTG mode.
There exists dubious and unbalanced put_device() call in musb_free() which
takes place only in the OTG mode.  As this commit caused musb_platform_exit()
to be called (and so unregister the NOP transceiver) before this put_device()
call, this function references already freed memory.

On the other hand, all the glue layers miss the otg_put_transceiver() call,
complementary to the otg_get_transceiver() call that they do.  So, I think
the solution is to get rid of the strange put_device() call, and instead
call otg_put_transceiver() in the glue layers...

230f7ede6c USB: add USB EHCI support for MPC5121 SoC
Extends FSL EHCI platform driver glue layer to support
MPC5121 USB controllers. MPC5121 Rev 2.0 silicon EHCI
registers are in big endian format. The appropriate flags
are set using the information in the platform data structure.
MPC83xx system interface registers are not available on
MPC512x, so the access to these registers is isolated in
MPC512x case. Furthermore the USB controller clocks
must be enabled before 512x register accesses which is
done by providing platform specific init callback.

The MPC512x internal USB PHY doesn't provide supply voltage.
For boards using different power switches allow specifying
DRVVBUS and PWR_FAULT signal polarity of the MPC5121 internal
PHY using "fsl,invert-drvvbus" and "fsl,invert-pwr-fault"
properties in the device tree USB nodes. Adds documentation
for this new device tree bindings.

commit 633ba7876b96ec339ef685357e2f7c60b5a8ce85 broke

This patch will only enable AUTOCLEAR if our endpoint's
FIFO was configured with double buffering support. Note
this is not a complete fix, double buffered case still
doesn't work always, but that hasn't been working for
quite some time. Other than reverting the entire commit
and breaking testusb with double buffered case again,
I decided it was better to fix the single buffered case
and spend more time fixing double buffered case properly.

ae6d22fe18 USB: Move USB Storage definitions to their own header file
The libusual header file is hard to use from code that isn't part
of libusual.  As the comment suggests, these definitions are moved to
their own header file, paralleling other USB classes.

1992de83e3 USB: qcserial: Enable Diagnostics Monitor and GPS ports on Gobi 2000
this patch to qcserial.c enables the Diagnostics Monitor
and NMEA GPS ports on Qualcomm Gobi 2000 devices.

A Gobi 2000 device will provide 3 serial ports:
        # /dev/ttyUSB0 -> Diagnostics
        # /dev/ttyUSB1 -> 3G Modem
        # /dev/ttyUSB2 -> NMEA GPS port

* The Diagnostics Monitor uses Qualcomm's DM protocol; I used
  libqcdm (ModemManager) to talk to it, found it working, but at
  least DM commands 12 and 64 are not implemented on my device
  (Gobi 2000 built into Thinkpad x100e).

* Functionality of the 3G Modem port remains unchanged.

* The GPS port and how to enable it has been confirmed now in the
  Gobi 3000 source code at:
	https://www.codeaurora.org/patches/quic/gobi/
  Enable/disable GPS via:
        echo "\$GPS_START" > /dev/ttyUSB2
        # use GPS
        echo "\$GPS_STOP"  > /dev/ttyUSB2

6195e3c6aa USB: cdc.h: ncm: fix one more typo
In usb_cdc_ncm_dpe32 the fields are 32 bit long and according
to usb style (hungarian notation) should be called dwDatagramIndex
and dwDatagramLength (see CDC NCM subclass spec, 3.3.2). Actually,
they were called wDatagramIndex, wDatagramLength.

677aeafe19 USB: ftdi_sio: revert "USB: ftdi_sio: fix DTR/RTS line modes"
This reverts commit 6a1a82df91.

RTS and DTR should not be modified based on CRTSCTS when calling
set_termios.

Modem control lines are raised at port open by the tty layer and should stay
raised regardless of whether hardware flow control is enabled or not.

This is in conformance with the way serial ports work today and many
applications depend on this behaviour to be able to talk to hardware
implementing hardware flow control (without the applications actually using
it).

Hardware which expects different behaviour on these lines can always
use TIOCMSET/TIOCMBI[SC] after port open to change them.
