This patch introduces the use of devm_request_irq, devm_gpio_request,
devm_clk_get etc. instead of the corresponding unmanaged interfaces. The
calls to the functions like free_irq to free the allocated resources are
removed as they are no longer required. Some labels in the probe function
are also done away with and the name of the label err_gpio_pullup is
changed to make it less specific to the context.

This patch adds support for the PLX USB3380 and USB3382.
This driver is based on the driver from the manufacturer.
Since USB338X is register compatible with NET2280, I thought that it
would be better to include this hardware into net2280 driver.
Manufacturer's driver only supported the USB33X, did not follow the
Kernel Style and contain some trivial errors. This patch has tried to
address this issues.
This patch has only been tested on USB338x hardware, but the merge has
been done trying to not affect the behaviour of NET2280.

The dependency on the isp1301 driver is not something that
should be in the main OHCI driver but rather the SoC specific
part of it.
This moves the dependency for LPC32xx into USB_OHCI_HCD_LPC32XX,
and changes the 'select ISP1301_OMAP' to a similar 'depends on'.
Since the same dependency exists for the client driver, do the

In some circumstances when g_audio is being unloaded there happens
an endless loop in udc driver. It has happend on a board with
s3c-hsotg. If there are requests in endpoint's queue, they are completed
in a loop. But completing them might cause appending new requests
to the queue. This patch causes agdev_iso_complete() to return immediately
if request's status is -ESHUTDOWN. If it does not return immediately,
then although the current request is removed from the queue, a new one
is appended to the queue, so the above mentioned loop cannot end.

Add handling of OS Extended Properties descriptors from configfs interface.
One kind of "OS Descriptors" are "Extended Properties" descriptors, which
need to be specified per interface or per group of interfaces described
by an IAD. This patch adds support for creating subdirectories
in interface.<n> directory located in the function's directory.
Names of subdirectories created become names of properties.
Each property contains two attributes: "type" and "data".
The type can be a numeric value 1..7 while data is a blob interpreted
depending on the type specified.
The types are:
1 - unicode string
2 - unicode string with environment variables
3 - binary
4 - little-endian 32-bit
5 - big-endian 32-bit
6 - unicode string with a symbolic link
7 - multiple unicode strings

Add handling of OS Extended Compatibility descriptors from configfs interface.
Hosts which expect the "OS Descriptors" ask only for configurations @ index 0,
but linux-based USB devices can provide more than one configuration.
This patch adds marking one of gadget's configurations the configuration
to be reported at index 0, regardless of the actual sequence of usb_add_config
invocations used for adding the configurations. The configuration is selected
by creating a symbolic link pointing to it from the "os_desc" directory
located at the top of a gadget's directory hierarchy.
One kind of "OS Descriptors" are "Extended Compatibility Descriptors",
which need to be specified per interface. This patch adds interface.<n>
directory in function's configfs directory to represent each interface
defined by the function. Each interface's directory contains two attributes:
"compatible_id" and "sub_compatible_id", which represent 8-byte
strings to be reported to the host as the "Compatible ID" and "Sub Compatible

If "use" contains "0" the OS string is not reported to the host.
"b_vendor_code" contains a one-byte value which is used

There is a custom (non-USB IF) extension to the USB standard:
http://msdn.microsoft.com/library/windows/hardware/gg463182
They grant permission to use the specification - there is
"Microsoft OS Descriptor Specification License Agreement"
under the link mentioned above, and its Section 2 "Grant
of License", letter (b) reads:
"Patent license. Microsoft hereby grants to You a nonexclusive,
royalty-free, nontransferable, worldwide license under Microsoft’s
patents embodied solely within the Specification and that are owned
or licensable by Microsoft to make, use, import, offer to sell,
sell and distribute directly or indirectly to Your Licensees Your
Implementation. You may sublicense this patent license to Your
Licensees under the same terms and conditions."
The said extension is maintained by Microsoft for Microsoft.
Yet it is fairly common for various devices to use it, and a
popular proprietary operating system expects devices to provide
"OS descriptors", so Linux-based USB gadgets whishing to be able
to talk to a variety of operating systems should be able to provide
the "OS descriptors".
This patch adds optional support for gadgets whishing to expose
the so called "OS Feature Descriptors", that is "Extended Compatibility ID"
and "Extended Properties".
Hosts which do request "OS descriptors" from gadgets do so during
the enumeration phase and before the configuration is set with
SET_CONFIGURATION. What is more, those hosts never ask for configurations
at indices other than 0. Therefore, gadgets whishing to provide
"OS descriptors" must designate one configuration to be used with
this kind of hosts - this is what os_desc_config is added for in
struct usb_composite_dev. There is an additional advantage to it:
if a gadget provides "OS descriptors" and designates one configuration
to be used with such non-USB-compliant hosts it can invoke
"usb_add_config" in any order because the designated configuration
will be reported to be at index 0 anyway.
This patch also adds handling vendor-specific requests addressed
at device or interface and related to handling "OS descriptors".
