1935e357bb USB: serial: metro-usb: convert to use module_usb_serial_driver
Now that we aren't doing anything special in the init function, move to
use the easier module_usb_serial_driver() call instead, saving a lot of
lines of unnecessary code.

All new usb serial drivers should be using the dynamic id function, not
having module parameters for this type of thing.  So remove them before
anyone gets used to them being there.

3cc3615749 usb: cdc-wdm: adding usb_cdc_wdm_register subdriver support
This driver can be used as a subdriver of another USB driver, allowing
it to export a Device Managment interface consisting of a single interrupt
endpoint with no dedicated USB interface.

Some devices provide a Device Management function combined with a wwan
function in a single USB interface having three endpoints (bulk in/out
+ interrupt).  If the interrupt endpoint is used exclusively for DM
notifications, then this driver can support that as a subdriver
provided that the wwan driver calls the appropriate entry points on
probe, suspend, resume, pre_reset, post_reset and disconnect.

The main driver must have full control over all interface related
settings, including the needs_remote_wakeup flag. A manage_power
function must be provided by the main driver.

A manage_power stub doing direct flag manipulation is used in normal
driver mode.

b0c1386080 usb: cdc-wdm: adding list lookup indirection
Register all interfaces handled by this driver in a list, getting
rid of the dependency on usb_set_intfdata.  This allows further
generalization and simplification of the probe/create functions.

This is needed to decouple wdm_open from the driver owning the
interface, and it also allows us to share all the code in
wdm_create with drivers unable to do usb_set_intfdata.

371f3b49f2 usb/core: remove "always" from usb_unlink_urb() kernel doc entry
The kernel doc entry for usb_unlink_urb() contains the phrase "This
request is always asynchronous.". The "always" leads to the assumption
that the ->complete() callback is not called from within
usb_unlink_urb(). This is not true. The HCD is allowed to call the
->complete() from within ->urb_dequeue() if it is appropriate for the
hardware.
This patch updates the kernel doc so usb-device driver authors make sure
to drop all locks (and make sure it is okay to drop them) which are
acquired by the complete callback before calling usb_unlink_urb().

2a5be8783e Allocate correct size (portably) in drivers/usb/gadget/f_midi.c::f_midi_bind()
As the coverity checker puts it:

"Passing argument "sizeof (midi_function) /*8*/" to function "kcalloc"
and then casting the return value to "struct usb_descriptor_header **"
is suspicious. ... In this particular case sizeof(struct
usb_descriptor_header **) happens to be equal to sizeof(struct
usb_descriptor_header *), but this is not a portable assumption."

I believe we really do intend to use 'sizeof(*midi_function)' here, so
this patch makes that change.

a5360a53a7 usb: cp210x: Update to support CP2105 and multiple interface devices
This patch updates the cp210x driver to support CP210x multiple
interface devices devices from Silicon Labs. The existing driver
always sends control requests to interface 0, which is hardcoded in
the usb_control_msg function calls. This only allows for single
interface devices to be used, and causes a bug when using ports on an
interface other than 0 in the multiple interface devices.

Here are the changes included in this patch:
- Updated the device list to contain the Silicon Labs factory default
  VID/PID for multiple interface CP210x devices
- Created a cp210x_port_private struct created for each port on
  startup, this struct holds the interface number
- Added a cp210x_release function to clean up the cp210x_port_private
  memory created on startup
- Modified usb_get_config and usb_set_config to get a pointer to the
  cp210x_port_private struct, and use the interface number there in the
  usb_control_message wIndex param

 The highlight on this merge is the support for Samsung's Exynos platform,
 increasing the number of different users for this driver to three.
 
 Note that Samsung Exynos glue layer will only compile on platforms which
 provide implementation for the clk API for now. Once Samsung supports
 pm_runtime, that limitation can be dropped from the Makefile.

f9b0f51709 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.

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

8062d94a54 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).

15e68a8035 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.

f7c96f59b4 Revert "powerpc/usb: fix usb CTRL_PHY_CLK_VALID breaks on some platform"
This reverts commit 79857e8e7b.

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.

aac1fc386f 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.
