USB: add reset endpoint operations

2009-04-17T17:50:27+00:00

Wireless USB endpoint state has a sequence number and a current
window and not just a single toggle bit.  So allow HCDs to provide a
endpoint_reset method and call this or clear the software toggles as
required (after a clear halt, set configuration etc.).

usb_settoggle() and friends are then HCD internal and are moved into
core/hcd.h and all device drivers call usb_reset_endpoint() instead.

If the device endpoint state has been reset (with a clear halt) but
the host endpoint state has not then subsequent data transfers will
not complete. The device will only work again after it is reset or
disconnected.

USB: make actual_length in struct urb field u32

2009-03-24T23:20:36+00:00

actual_length should also be a u32 and not a signed value.  This patch
changes this field to be 'u32' to prevent any potential negative
conversion and comparison errors.

This triggered a few compiler warning messages when these fields were
being used with the min macro, so they have also been fixed up in this
patch.

USB: make transfer_buffer_lengths in struct urb field u32

2009-03-24T23:20:36+00:00

Roel Kluin pointed out that transfer_buffer_lengths in struct urb was
declared as an 'int'.  This patch changes this field to be 'u32' to
prevent any potential negative conversion and comparison errors.

This triggered a few compiler warning messages when these fields were
being used with the min macro, so they have also been fixed up in this
patch.

USB: Move definitions from usb.h to usb/ch9.h

2009-03-24T23:20:27+00:00

The functions:

usb_endpoint_dir_in(epd)
usb_endpoint_dir_out(epd)
usb_endpoint_is_bulk_in(epd)
usb_endpoint_is_bulk_out(epd)
usb_endpoint_is_int_in(epd)
usb_endpoint_is_int_out(epd)
usb_endpoint_is_isoc_in(epd)
usb_endpoint_is_isoc_out(epd)
usb_endpoint_num(epd)
usb_endpoint_type(epd)
usb_endpoint_xfer_bulk(epd)
usb_endpoint_xfer_control(epd)
usb_endpoint_xfer_int(epd)
usb_endpoint_xfer_isoc(epd)

are moved from include/linux/usb.h to include/linux/usb/ch9.h.
include/linux/usb/ch9.h makes more sense for these functions because they
only depend on constants that are defined in this file.

USB: remove info() macro from usb.h

2009-01-07T18:00:14+00:00

USB should not be having it's own printk macros, so remove info() and
use the system-wide standard of dev_info() wherever possible.

No one in the tree is using the macro, so it can now be removed.

USB: remove warn() macro from usb.h

2009-01-07T18:00:14+00:00

USB should not be having it's own printk macros, so remove warn() and
use the system-wide standard of dev_warn() wherever possible.  In the
few places that will not work out, use a basic printk().

Now that all in-tree users are gone, remove the macro.

USB: extension of anchor API to unpoison an anchor

2009-01-07T18:00:11+00:00

This extension allows unpoisoning an anchor allowing drivers that
resubmit URBs to reuse an anchor for methods like resume()

USB: mark "reject" field of struct urb as atomic_t

2009-01-07T18:00:08+00:00

It is enough to protect accesses to reject field of urb
by marking it as atomic_t,also it is the only reason of
existence of usb_reject_lock,so remove the lock to make
code more clean.

USB: utilize the bus notifiers

2009-01-07T18:00:08+00:00

This patch (as1185) makes usbcore take advantage of the bus
notifications sent out by the driver core.  Now we can create all our
device and interface attribute files before the device or interface
uevent is broadcast.

A side effect is that we no longer create the endpoint "pseudo"
devices at the same time as a device or interface is registered -- it
seems like a bad idea to try registering an endpoint before the
registration of its parent is complete.  So the routines for creating
and removing endpoint devices have been split out and renamed, and
they are called explicitly when needed.  A new bitflag is used for
keeping track of whether or not the interface's endpoint devices have
been created, since (just as with the interface attributes) they vary
with the altsetting and hence can be changed at random times.
