Greg Kroah-Hartman 0c8b1992b4 USB: gadget: fix up some comments about CONFIG_USB_DEBUG
These two gadget drivers said that their #endif was for
CONFIG_USB_DEBUG, but they really were not, so fix them up to be
correct.

Andrzej Pietrasiewicz e5eaa0dc48 usb: gadget: f_mass_storage: convert to new function interface with backward compatibility
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.

Andrzej Pietrasiewicz 6fdc5dd25e usb: gadget: create a utility module for mass_storage
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.

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

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.

Sebastian Andrzej Siewior 19b10a8828 usb: gadget: allocate & giveback serial ports instead hard code them
This patch removes gserial_setup() and gserial_cleanup() and adds
gserial_alloc_line() and gserial_free_line() to replace them.

The initial setup of u_serial happens now on module load time. A
maximum of four TTY ports can be requested which is the current limit.
In theory we could extend this limit, the hard limit is the number of
available endpoints.
alloc_tty_driver() is now called at module init time with the max
available ports. The per-line footprint here is on 32bit is 3 * size of
pointer + 60 bytes (for cdevs).
The remaining memory (struct gs_port) is allocated once a port is
requested.

With this change it is possible to load g_multi and g_serial at the same
time. GS0 receives the module that is loaded first, GS1 is received by
the next module and so on. With the configfs interface the port number
can be exported and the device node is more predictable. Nothing changes
for g_serial and friends as long as one module is used.

There is one limition with this: ports and and gs_tty_driver are global

user loaded at a time i.e. either g_serial or g_nokia.

Sebastian Andrzej Siewior ed9cbda63d usb: gadget: remove usb_gadget_controller_number()
The bcdDevice field is defined as
|Device release number in binary-coded decimal
in the USB 2.0 specification. We use this field to distinguish the UDCs
from each other. In theory this could be used on the host side to apply
certain quirks if the "special" UDC in combination with this gadget is
used. This hasn't been done as far as I am aware. In practice it would
be better to fix the UDC driver before shipping since a later release
might not need this quirk anymore.

There are some driver in tree (on the host side) which use the bcdDevice
field to figure out special workarounds for a given firmware revision.
This seems to make sense. Therefore this patch converts all gadgets
(except a few) to use the kernel version instead a random 2 or 3 plus
the UDC number. The few that don't report kernel's version are:
- webcam
  This one reports always a version 0x10 so allow it to do so in future.
- nokia
  This one reports always 0x211. The comment says that this gadget works
  only if the UDC supports altsettings so I added a check for this.
- serial
  This one reports 0x2400 + UDC number. Since the gadget version is 2.4
  this could make sense. Therefore bcdDevice is 0x2400 here.

I also remove various gadget_is_<name> macros which are unused. The
remaining few macros should be moved to feature / bug bitfield.

Some gadgets provide custom entry here. Some may override it with an
etntry that is also created by composite if there was no value sumbitted
at all.
This patch removes all "custom manufacturer" strings which are the same
as these which are created by composite. Then it moves the creation of
the default manufacturer string to usb_composite_overwrite_options() in
case no command line argument has been used and the entry is still an
empty string.
By doing this we get rid of the global variable "composite_manufacturer"
in composite.

used to add it to USB configuration.  Renamed as to match
naming convention of other functions.

Michal Nazarewicz dbe4a99d84 USB: g_multi: fix CONFIG_USB_G_MULTI_RNDIS usage
g_multi used CONFIG_USB_ETH_RNDIS to check if RNDIS option was requested
where it should check for CONFIG_USB_G_MULTI_RNDIS.  As a result, RNDIS
was never present in g_multi regardless of configuration.

This fixes changes made in commit 396cda90d2.

Michal Nazarewicz 396cda90d2 USB: Added USB_ETH_RNDIS to use instead of CONFIG_USB_ETH_RNDIS
If g_ether and g_multi are both built CONFIG_USB_ETH_RNDIS symbol
may be redefined in the later and, whats even worse, g_ether's settings
may affect g_multi's.  This adds a USB_ETH_RNDIS symbol defined at the
beginning of ether.c and multi.c according toproper KConfig settings.

Michal Nazarewicz f176a5d812 USB: g_multi: Multifunction Composite Gadget added
The Multifunction Composite Gadget has two configurations
consisting of Ethernet (RNDIS in first and CDC Ethernet in
second configuration), CDC Serial and File-backed Storage
functions.

When connected to a Windows host, the first configuration
is chosen thus gadget provides RNDIS Ethernet, serial and
mass storage whereas when connected to Linux host, second
configuration is chosen thus providing CDC Ethernet,
serial and mass storage.

Which configurations are built can be configured via
KConfig options.
