USB: fix limited_power setting mistake in hub.c
This patch (jx001) fixes a variable assignment mistake in hub driver.
limited_power should be set to 0 if the hub is self-powered,and 1 if
the hub is bus-powered.
However, the effect of the code was exactly opposite to the spec's
statement for the Local Power Source field. The spec says, this field
is 1 meaning Local power supply lost while this field is 0 indicating
Local power supply good.(This statement is very confusing.)
So this patch switchs the 0 and 1.

USB: usb-skeleton leaking locks on open
This weekend I was hacking around with a trivial USB driver for talking
to the boot load firmware of a USB Bit Whacker. It's running the
MicroChip Pic18 boot loader firmware and I'm putting together a flash
program for writing new FW to the thing.
Anyway in my use of the usb-skeleton.c as my starting point I discovered
my test program was getting hung up after attempting to write a buffer.
The application and driver where hung in a way that required me to
reboot to get it to clean up so I could try again.
It turned out the code path through skel_open can grap the driver's
io_mutex lock and forget to release it.
The following patch fixes the problem for me.

USB: flush outstanding URBs when suspending
This patch (as989) makes usbcore flush all outstanding URBs for each
device as the device is suspended. This will be true even when
CONFIG_USB_SUSPEND is not enabled.
In addition, an extra can_submit flag is added to the usb_device
structure. That flag will be turned off whenever a suspend request
has been received for the device, even if the device isn't actually
suspended because CONFIG_USB_SUSPEND isn't set.
It's no longer necessary to check for the device state being equal to
USB_STATE_SUSPENDED during URB submission; that check can be replaced
by a check of the can_submit flag. This also permits us to remove
some questionable references to the deprecated power.power_state field.

USB: break apart flush_endpoint and disable_endpoint
This patch (as988) breaks usb_hcd_endpoint_disable() apart into two
routines. The first, usb_hcd_flush_endpoint() does the -ESHUTDOWN
unlinking of all URBs in the endpoint's queue and waits for them to
complete. The second, usb_hcd_disable_endpoint() -- renamed for
better grammatical style -- merely calls the HCD's endpoint_disable
method. The changeover is easy because the routine currently has only
one caller.
This separation of function will be exploited in the following patch:
When a device is suspended, the core will be able to cancel all
outstanding URBs for that device while leaving the HCD's
endpoint-related data structures intact for later.
As an added benefit, HCDs no longer need to check for existing URBs in
their endpoint_disable methods. It is now guaranteed that there will
be none.

USB: make HCDs responsible for managing endpoint queues
This patch (as954) implements a suggestion of David Brownell's. Now
the host controller drivers are responsible for linking and unlinking
URBs to/from their endpoint queues. This eliminates the possiblity of
strange situations where usbcore thinks an URB is linked but the HCD
thinks it isn't. It also means HCDs no longer have to check for URBs
being dequeued before they were fully enqueued.
In addition to the core changes, this requires changing every host
controller driver and the root-hub URB handler. For the most part the
required changes are fairly small; drivers have to call
usb_hcd_link_urb_to_ep() in their urb_enqueue method,
usb_hcd_check_unlink_urb() in their urb_dequeue method, and
usb_hcd_unlink_urb_from_ep() before giving URBs back. A few HCDs make
matters more complicated by the way they split up the flow of control.
In addition some method interfaces get changed. The endpoint argument
for urb_enqueue is now redundant so it is removed. The unlink status
is required by usb_hcd_check_unlink_urb(), so it has been added to
urb_dequeue.

Effectively this means that we have to clean all the configuration
descriptors on deauthorize and reload them when we authorized. We could
do without throwing them out for wired devices, but for wireless, we can
read them only after authenticating, and thus, when authorizing an
authenticated device we would need to read them. So to simplify, always
release them on deauthorize(), re-read them on authorize().

bNumConfigurations was being set to zero before the for loop, and thus

- The actual actions of adding a new device (quirk detection,

- Actual discovery and probing of the configuration and interfaces
(split into __usb_configure_device())
- Configuration of the On-the-go parameters (split into
__usb_configure_device_otg()).
The fundamental reasons for doing this split are clarity (smaller
functions are easier to maintain) and to allow part of the code to be
reused when authorizing devices to connect.
When a device is authorized connection, we need to run through the
hoops we didn't run when it was connected but not authorized, which is
basically parsing the configurations and probing

shrink object code and remove #ifdeffery.
- gadget_is_dualspeed(), currently always a compile-time
constant (depending on which controller is selected).
- gadget_is_otg(), usually a compile time "false", but this
is a runtime test if the platform enables OTG (since it's
reasonable to populate boards with different USB sockets).
It also updates two peripheral controller drivers to use these:
- fsl_usb2_udc, mostly OTG-related bugfixes: non-OTG devices
must follow the rules about drawing VBUS power, and OTG ones
need to reject invalid SET_FEATURE requests.
- omap_udc, just scrubbing a bit of #ifdeffery.

these functions will be called directly by host controller drivers
while holding their private spinlocks, which will remove the
possibility of some unpleasant races.
The code responsible for mapping and unmapping DMA buffers is also
placed into a couple of separate subroutines, for the sake of
cleanliness and consistency.

USB: update spinlock usage for root-hub URBs
This patch (as952) adjusts the spinlock usage in the root-hub
emulation part of usbcore, to make it match more closely the pattern
used by regular host controller drivers. To wit: The private lock
(usb_hcd_root_hub_lock) is held throughout the important parts, and it
is dropped temporarily without re-enabling interrupts around the call
to usb_hcd_giveback_urb().
A nice side effect is that the code now avoids calling
local_irq_save(), thereby becoming more RT-friendly.

USB: cleanup for previous patches
This patch (as951) cleans up a few loose ends from earlier patches.
Redundant checks for non-NULL urb->dev are removed, as are checks of
urb->dev->bus (which can never be NULL). Conversely, a check for
non-NULL urb->ep is added to the unlink paths.
A homegrown round-down-to-power-of-2 loop is simplified by using the
ilog2 routine. The comparison in usb_urb_dir_in() is made more
transparent.

USB: avoid urb->pipe in usbfs
This patch (as948) removes most of the references to urb->pipe from
the usbfs routines in devio.c. The one tricky aspect is in
snoop_urb(), which can be called before the URB is submitted and which
uses usb_urb_dir_in(). For this to work properly, the URB's direction
flag must be set manually in proc_do_submiturb().
The patch also fixes a minor bug; the wValue, wIndex, and wLength
fields were snooped in proc_do_submiturb() without conversion from
le16 to CPU-byte-ordering.

USB: address-0 handling during device initialization
This patch (as947) changes the device initialization and enumeration
code in hub.c; now udev->devnum will be set to 0 while the device is
being accessed at address 0. Until now this wasn't needed because the
address value was passed as part of urb->pipe; without that field the
device address must be stored elsewhere.

USB: avoid using urb->pipe in usbcore
This patch (as946) eliminates many of the uses of urb->pipe in
usbcore. Unfortunately there will have to be a significant API
change, affecting all USB drivers, before we can remove it entirely.
This patch contents itself with changing only the interface to
usb_buffer_map_sg() and friends: The pipe argument is replaced with a
direction flag. That can be done easily because those routines get
used in only one place.

USB: add direction bit to urb->transfer_flags
This patch (as945) adds a bit to urb->transfer_flags for recording the
direction of the URB. The bit is set/cleared automatically in
usb_submit_urb() so drivers don't have to worry about it (although as
a result, it isn't valid until the URB has been submitted). Inline
routines are added for easily checking an URB's direction. They
replace calls to usb_pipein in the DMA-mapping parts of hcd.c.
For non-control endpoints, the direction is determined directly from
the endpoint descriptor. However control endpoints are
bi-directional; for them the direction is determined from the
bRequestType byte and the wLength value in the setup packet.

USB: add ep->enable
This patch (as944) adds an explicit "enabled" field to the
usb_host_endpoint structure and uses it in place of the current
mechanism. This is merely a time-space tradeoff; it makes checking
whether URBs may be submitted to an endpoint simpler. The existing
mechanism is efficient when converting urb->pipe to an endpoint
pointer, but it's not so efficient when urb->ep is used instead.
As a side effect, the procedure for enabling an endpoint is now a
little more complicated. The ad-hoc inline code in usb.c and hub.c
for enabling ep0 is now replaced with calls to usb_enable_endpoint,
which is no longer static.
