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.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC driver specific changes from Arnd Bergmann:
"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."

USB_CONFGFS_ZZZZ should appear under a tristate option in order to allow
selecting more than one function without building the legacy gadgets.
Now there are two problems:
1) they can't be selected at all, because they depend on USB_CONFIGFS,
and the patch which adds USB_CONFIGFS has not been merged.
2) they don't select USB_LIBCOMPOSITE (which they need but which is
selected by USB_CONFIGFS)

usb: patches for v3.10 merge window
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.

This patch converts the f_obex.c to the new function interface.
The file is now compiled into a separate usb_f_obex.ko module.
The old function interface is provided by means of preprocessor
conditional directives. After all users are converted, the old interface
can be removed.

v5…v6
- 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 converts the acm_ms gadget to make use of the function
framework to request the ACM function.
The "old" include interface for acm is now removed since nokia was the
last user of it (for ACM).

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.
