Currently, 'res->flags' handlings are wrong in three respects:
* the driver _modifies_ the contents of platform data
* res->flags is set up, but not used anywhere in the driver
* request_irq() always takes VBUS_IRQ_FLAGS, regardless of refs->flags

This patch tries to fix this with a policy: If a platform IRQ resource
is available, give preference to its IRQ flag(s) over a default one
(VBUS_IRQ_FLAGS).

gpio_vbus is designed to be able to get an IRQ number for VBUS change
interrupt either (1) through platform_get_resource(IORESOURCE_IRQ) or
(2) by processing gpio_to_irq(pdata->gpio_vbus), in probe() function.

On the other hand, gpio_vbus_set_peripheral() and gpio_vbus_remove()
are always doing gpio_to_irq(pdata->gpio_vbus) to get an IRQ number.

This is not just inconsistent, but also broken.  There is no guarantee
that an IRQ number obtained by platform_get_resource() is equal to
gpio_to_irq(pdata->gpio_vbus).

Cache an IRQ number in probe() function, and use it where necessary.

Add FunctionFS support.
It allows certain USB functions to be provided from userspace, e.g. MTP,
PTP, adb.

The functions provided by the gadget itself are enumerated in
/sys/class/ccg0/functions. The functions which can be supplied
from userspace must be enumerated in /sys/class/ccg0/f_fs/user_functions.
No other userspace functions can be used than specified in the above mentioned
file, but just specifying them there is not enough to activate them.
The userspace functions in order to be activated need also be enumerated
in /sys/class/ccg0/functions.

An example sequence of operations can be as follows:

$ echo 0 > /sys/class/ccg_usb/ccg0/enable

$ echo -n 0x2d01 > /sys/module/g_ccg/parameters/idProduct
$ echo -n MyDevice > /sys/module/g_ccg/parameters/iSerialNumber
$ echo -n 0x1d6b > /sys/module/g_ccg/parameters/idVendor
$ echo -n Manufacturer > /sys/module/g_ccg/parameters/iManufacturer
$ echo -n Product > /sys/module/g_ccg/parameters/iProduct
$ echo -n bcdDevice > /sys/module/g_ccg/parameters/bcdDevice

$ echo adb,mtp,ptp > /sys/class/ccg_usb/ccg0/f_fs/user_functions
$ echo mass_storage,ptp > /sys/class/ccg_usb/ccg0/functions
$ echo /file.img > /sys/class/ccg_usb/ccg0/f_mass_storage/lun/file

$ mkdir -p /dev/usbgadget/ptp
$ mount -t functionfs ptp /dev/usbgadget/ptp
$ ./ptp &

$ echo 1 > /sys/class/ccg_usb/ccg0/enable

The above example declares that adb, mtp and ptp functions can be supplied
from userspace through FunctionFS. But of them all only ptp is actually
activated, together with mass_storage, the latter being implemented in
the gadget itself (in kernel, not in userspace). The list of functions
can be modified at runtime while the gadget is not enabled, that is,
after

$ echo 0 > /sys/class/ccg_usb/ccg0/enable

The FunctionFS function is implicitly handled by the gadget, that is,
if a userspace function name is provided in
/sys/class/ccg_usb/ccg0/functions, then the FunctionFS function
is activated.

The Configurable Gadget driver is a composite driver that allows
userspace to change at runtime the list of functions enabled in
its configuration and to configure these functions. It supports
multiple functions: acm, rndis, and mass storage.

It is usually controlled by a daemon that changes the configuration
based on user settings. For example, rndis is enabled when the user
enables sharing the phone data connection.

As an example on how to use it, the following shell commands will
make the gadget disconnect from the host and make it be re-enumerated
as a composite with 1 rndis and 2 acm interfaces, and a different
product id:

echo 0       > /sys/class/ccg_usb/ccg0/enable
echo rndis,acm > /sys/class/ccg_usb/ccg0/functions
echo 2       > /sys/class/ccg_usb/ccg0/f_acm/instances
echo -n 0x2d01 > /sys/module/g_ccg/parameters/idProduct
echo 1       > /sys/class/ccg_usb/ccg0/enable

The driver requires a gadget controller that supports software
control of the D+ pullup and the controller driver must support
disabling the pullup during composite_bind.

Commit da0af6e7 ("usb: Bind devices to ACPI devices when possible") really
tries to force-bind devices even when impossible, unlike what it says in
the subject.

CONFIG_ACPI is not an indication that ACPI tables are actually present, nor
is an indication that any USB relevant information is present in them. There
is no reason to fail the creation of a USB bus if it can't bind it to
ACPI device during initialization.

On systems with CONFIG_ACPI set but without ACPI tables it would cause a
boot panic.

Now that the usb-serial core supports reset_resume, put this driver

This patch (as1556) works around a bug in the Philips ISP1562 EHCI
controller.  Although the controller claims to support frame-list
lengths smaller than the default of 1024 for its periodic schedule, in
fact smaller values don't work.  A new quirk flag is added to indicate
when the bug is present, and if it is then the schedule size is left
at the default value.

This patch (as1555) improves the code ehci-hcd uses while checking the
periodic schedule for isochronous transfers to full-speed devices.  In
addition to making sure that a new transfer does not violate the
restrictions on the high-speed schedule, it also has to check the
restrictions on the full-speed part of the bus, i.e., the part beyond
the Transaction Translator (TT).

It does this by calling tt_available() (or tt_no_collision() if
CONFIG_USB_EHCI_TT_NEWSCHED isn't enabled).  However it calls that
routine on each pass through a loop over the frames being modified,
which is an unnecessary expense because tt_available() (or
tt_no_collision) already does its own loop over frames.  It is
sufficient to do the check just once, before starting the loop.

In addition, the function calls incorrectly converted the transfer's
period from microframes to frames by doing a left shift instead of a
right shift.  The patch fixes this while moving the calls.
