Converting mass storage to the new function interface requires converting
the USB mass storage's function code and its users.
This patch converts the f_mass_storage.c to the new function interface.
The file is now compiled into a separate usb_f_mass_storage.ko module.
The old function interface is provided by means of a preprocessor conditional
directives. After all users are converted, the old interface can be removed.

Converting to configfs requires making the f_mass_storage.c a module.
But first we need to get rid of "#include "storage_common.c".
This patch makes storage_common.c a separately compiled file, which is
built as a utility module named u_ms.ko. After all mass storage users are
converted to the new function interface this module can be eliminated
by merging it with the mass storage function's module.
USB descriptors are exported so that they can be accessed from
f_mass_storage.
FSG_VENDOR_ID and FSG_PRODUCT_ID are moved to their only user.
Handling of CONFIG_USB_GADGET_DEBUG_FILES is moved to f_mass_storage.c.
The fsg_num_buffers static is moved to FSG_MODULE_PARAMETER users, so
instead of using a global variable the f_mass_storage introduces
fsg_num_buffers member in fsg_common (and fsg_config).
fsg_strings and fsg_stringtab are moved to f_mass_storage.c.

Convert PHY Drivers from menuconfig to menu so that the PHY drivers
can be explicitely selected by the controller drivers.
USB_PHY is no longer a user visible option. It is upto to the PHY
drivers to select it if needed. This patch does so for the existing
PHY drivers that use the USB_PHY library.
Doing so moves the USB_PHY and PHY driver selection problem from the
end user to the PHY and controller driver developer.
e.g.
Earlier, a controller driver (e.g. EHCI_OMAP) that needs to select
a PHY driver (e.g. NOP_PHY) couldn't do so because the PHY driver
depended on USB_PHY. Making the controller driver depend on USB_PHY
has a negative effect i.e. it becomes invisible to the user till
USB_PHY is enabled. Most end users will not familiar with this.
With this patch, the end user just needs to select the controller driver
needed for his/her platform without worrying about which PHY driver to
select.
Also update USB_EHCI_MSM, USB_LPC32XX and USB_OMAP to not depend
on USB_PHY any more. They can safely select the necessary PHY drivers.

That driver hasn't been really maintained for
a long time. It doesn't compile in any way, it
includes non-existent headers, has no users,
and is just plain broken.
The person who used to work with that driver
has publicly stated that he has no plans to
touch that driver again and is ok with removal[1].
Due to these factors, imx_udc is now removed from
the tree, if someone really believe it needs to
be kept, please fix the bugs in that driver.

These changes are all driver specific and cross over between arm-soc
contents and some other subsystem, in these cases cpufreq, crypto,
dma, pinctrl, mailbox and usb, and the subsystem owners agreed to
have these changes merged through arm-soc. As we proceed to untangle
the dependencies between platform code and driver code, the amount of
changes in this category is fortunately shrinking, for 3.11 we have
16 branches here and 101 non-merge changesets, the majority of which
are for the stedma40 dma engine driver used in the ux500 platform.
Cleaning up that code touches multiple subsystems, but gets rid
of the dependency in the end.
The mailbox code moved out from mach-omap2 to drivers/mailbox
is an intermediate step and is still omap specific at the moment.
Patches exist to generalize the subsystem and add other drivers
with the same API, but those did not make it for 3.11.

u_ether.c has been #include'd by all gadgets which implement
USB Ethernet functions. In order to add configfs support,
the f_ecm.c, f_eem.c, f_ncm.c, f_subset.c, f_rndis.c need to be
converted into modules and must not be #include'd. Consequently,
the u_ether.c needs to be a module too, in a manner similar
to u_serial.c. The resulting module should not take any parameters,
so they are pushed to the current users of it, that is ether.c,
g_ffs.c, multi.c, ncm.c, nokia.c.

Here is the big Gadget & PHY pull request. Many of us have
been really busy lately getting multiple drivers to a better
position.
Since this pull request is so large, I will divide it in sections
so it's easier to grasp what's included.
- cleanups:
. UDC drivers no longer touch gadget->dev, that's now udc-core
responsibility
. Many more UDC drivers converted to usb_gadget_map/unmap_request()
. UDC drivers no longer initialize DMA-related fields from gadget's
device structure
. UDC drivers don't touch gadget.dev.driver directly
. UDC drivers don't assign gadget.dev.release directly
. Removal of some unused DMA_ADDR_INVALID
. Introduction of CONFIG_USB_PHY
. All phy drivers have been moved to drivers/usb/phy and renamed to
a common naming scheme
. Fix PHY layer so it never returns a NULL pointer, also fix all
callers to avoid using IS_ERR_OR_NULL()
. Sparse fixes all over the place
. drivers/usb/otg/ has been deleted
. Marvel drivers (mv_udc, ehci-mv, mv_otg and mv_u3d) improved clock
usage
- new features:
. UDC core now provides a generic way for tracking and reporting
UDC's state (not attached, resuming, suspended, addressed,
default, etc)
. twl4030-usb learned that it shouldn't be enabled during init
. Full DT support for DWC3 has been implemented
. ab8500-usb learned about pinctrl framework
. nop PHY learned about DeviceTree and regulators
. DWC3 learned about suspend/resume
. DWC3 can now be compiled in host-only and gadget-only (as well as
DRD) configurations
. UVC now enables streaming endpoint based on negotiated speed
. isp1301 now implements the PHY API properly
. configfs-based interface for gadget drivers which will lead to
the removal of all code which just combines functions together
to build functional gadget drivers.
. f_serial and f_obex were converted to new configfs interface while
maintaining old interface around.
- non-critical fixes:
. UVC gadget driver got fixes for Endpoint usage and stream calculation
. ab8500-usb fixed unbalanced clock and regulator API usage
. twl4030-usb got a fix for when OMAP3 is booted with cable connected
. fusb300_udc got a fix for DMA usage
. UVC got fixes for two assertions of the USB Video Class Compliance
specification revision 1.1
. build warning issues caused by recent addition of __must_check to
regulator API
These are all changes which deserve a mention, all other changes are related
to these one or minor spelling fixes and other similar tasks.

- wired up strings with usb_gstrings_attach()
- add UDC attribe. Write "udc-name" will bind the gadget. Write an empty
string (it should contain \n since 0 bytes write get optimzed away)
will unbind the UDC from the gadget. The name of available UDCs can be
obtained from /sys/class/udc/
v4…v5
- string rework. This will add a strings folder incl. language code like
strings/409/manufacturer
as suggested by Alan.
- rebased ontop reworked functions.c which has usb_function_instance
which is used prior after "mkdir acm.instance" and can be directly
used for configuration via configfs.
v3…v4
- moved functions from the root folde down to the gadget as suggested
by Michał
- configs have now their own configs folder as suggested by Michał.
The folder is still name.bConfigurationValue where name becomes the
sConfiguration. Is this usefull should we just stilc
configs/bConfigurationValue/ ?
- added configfs support to the ACM function. The port_num attribute is
exported by f_acm. An argument has been added to the USB alloc
function to distinguish between "old" (use facm_configure() to
configure and configfs interface (expose a config_node).
The port_num is currently a dumb counter. It will
require some function re-work to make it work.
scheduled for v5:
- sym linking function into config.
v2…v3
- replaced one ifndef by ifdef as suggested by Micahał
- strstr()/strchr() function_make as suggested by Micahł
- replace [iSerialNumber|iProduct|iManufacturer] with
[sSerialNumber|sProduct|sManufacturer] as suggested by Alan
- added creation of config descriptors
v1…v2
- moved gadgets from configfs' root directory into /udcs/ within our
"usb_gadget" folder. Requested by Andrzej & Michał
- use a dot as a delimiter between function's name and its instance's name
as suggested by Michał
- renamed all config_item_type, configfs_group_operations, make_group,
drop_item as suggested by suggested by Andrzej to remain consisten
within this file and within other configfs users
- Since configfs.c and functions.c are now part of the udc-core module,
the module itself is now called udc. Also added a tiny ifdef around
init code becuase udc-core is subsys init and this is too early for
configfs in the built-in case. In the module case, we can only have
one init function.

This patch reworks the videobuffer management logic present in the UVC
webcam gadget and ports it to use the "more apt" videobuf2 framework for
video buffer management.
To support routing video data captured from a real V4L2 video capture
device with a "zero copy" operation on videobuffers (as they pass from
the V4L2 domain to UVC domain via a user-space application), we need to
support USER_PTR IO method at the UVC gadget side.
So the V4L2 capture device driver can still continue to use MMAP IO
method and now the user-space application can just pass a pointer to the
video buffers being dequeued from the V4L2 device side while queueing
them at the UVC gadget end. This ensures that we have a "zero-copy"
design as the videobuffers pass from the V4L2 capture device to the UVC
gadget.
Note that there will still be a need to apply UVC specific payload
headers on top of each UVC payload data, which will still require a copy
operation to be performed in the 'encode' routines of the UVC gadget.
This patch also addresses one issue found out while porting the UVC
gadget to videobuf2 framework:
- In case the usb requests queued by the gadget get completed
with a status of -ESHUTDOWN (disconnected from host),
the queue of videobuf2 should be cancelled to ensure that the
application space daemon is not left in a state waiting for
a vb2 to be successfully absorbed at the USB side.

This patch converts the f_sourcesink and f_loopback file to the USB-function
module. Both functions shares a few common utility functions which are
currently implemented in g_zero.c itself. This patch moves the common
code into the sourcesink file and creates one module out of the the two
functions (source sink and loop back).

The option allows you to remove TTY and compile without errors. This
saves space on systems that won't support TTY interfaces anyway.
bloat-o-meter output is below.
The bulk of this patch consists of Kconfig changes adding "depends on
TTY" to various serial devices and similar drivers that require the TTY
layer. Ideally, these dependencies would occur on a common intermediate
symbol such as SERIO, but most drivers "select SERIO" rather than
"depends on SERIO", and "select" does not respect dependencies.

This commit removes USB_GADGET_DUALSPEED and USB_GADGET_SUPERSPEED
Kconfig options. Since now kernel allows many UDC drivers to be
compiled, those options may turn to no longer be valid. For
instance, if someone decides to build UDC that supports super
speed and UDC that supports high speed only, the latter will be
"assumed" to support super speed since USB_GADGET_SUPERSPEED will
be selected by the former.
The test of whether CONFIG_USB_GADGET_*SPEED was defined was just
an optimisation which removed otherwise dead code (ie. if UDC is
not dual speed, there is no need to handle cases that can happen
if speed is high). This commit removes those checks.

so there is no need for this one any more.

Since chipidea is a dual role controller, it makes sense to move it
to its own directory, where we can also have host, otg and platform
code related to this controller. It also makes sense to break out
the driver into several compilation units like udc, host, debugging
code, etc.
Firstly, let's move the udc and platform code to drivers/usb/chipidea.

This fabric uses the target framework to provide a usb gadget
device. This gadget supports the USB Attached SCSI Protocol (UASP)
and Bulk Only Transfers (BOT or BBB). BOT is the primary interface,
UAS is the alternative interface.
It has been tested with dummy_hcd on HS and SS. On SS USB3 are
supported. I also took my omap device and tried it there against
WindowsXP. UAS implements basic command passing (i.e. read/write
requests) and TASK MANAGEMENT functions are missing.
I had to add a little of error recovery to BOT because Windows was
issuing some strange commands and it does not complain after the
gadget responded with CSW.status=1.
(nab: Move to drivers/usb/gadget as per Sebastian to address legacy
limitations for built-in gadget code)

Let's break ci13xxx driver into a separate udc driver and platform
drivers _pci and _msm, which will create a platform device for each pci
(or msm) device found. The approach was introduced by Felipe in dwc3
driver and there seems to be no reason not to use it.
msm related code is only compile-tested.
