Documentation/usb/WUSB-Design-overview.txt states that UWB devices seen
by a UWB radio controller are added to /sys/bus/uwb/devices, but this
was not actually being done. This functionality is needed in order for
UWB peer devices to be enumerated by user mode tools. This patch
creates a uwb bus type and adds UWB peer devices to it as they are
discovered by the radio controller.Signed-off-by: Thomas Pugliese

This patch fixes a race condition that caused the HWA_HC interface probe
function to occasionally fail. The HWA_HC would attempt to register
itself with the HWA_RC by searching for a uwb_rc class device with the
same parent device ptr. If the probe function for the HWA_RC interface
had yet to run, the uwb_rc class device would not have been created
causing the look up to fail and the HWA_HC probe function to return an
error causing the device to be unusable.The fix is for the HWA to delay registering with the HWA_RC until
receiving the command from userspace to start the wireless channel. It
is the responsibility of userspace to ensure that the uwb_rc class
device has been created before starting the HWA channel.Signed-off-by: Thomas Pugliese

It was pointed out by 'make versioncheck' that a include of
linux/version.h is not needed in drivers/uwb/uwb-internal.h .
This patch removes it.Signed-off-by: Jesper Juhl

In the future, we are going to be changing the lock type for struct
device (once we get the lockdep infrastructure properly worked out) To
make that changeover easier, and to possibly burry the lock in a
different part of struct device, let's create some functions to lock and
unlock a device so that no out-of-core code needs to be changed in the
future.This patch creates the device_lock/unlock/trylock() functions, and
converts all in-tree users to them.Cc: Thomas Gleixner

Greatly enhance the MAS allocator:
- Handle row and column reservations.
- Permit all the available MAS to be allocated.
- Follows the WiMedia rules on MAS selection.Take appropriate action when reservation conflicts are detected.
- Correctly identify which reservation wins the conflict.
- Protect alien BP reservations.
- If an owned reservation loses, resize/move it.
- Follow the backoff procedure before requesting additional MAS.When reservations are terminated, move the remaining reservations (if
necessary) so they keep following the MAS allocation rules.Signed-off-by: Stefano Panella

The UWB radio manager coordinates the use of the radio between the
PALs that may be using it. PALs request use of the radio with
uwb_radio_start() and the radio manager will start beaconing if its
not already doing so. When the last PAL has called uwb_radio_stop()
beaconing will be stopped.In the future, the radio manager will have a more sophisticated channel
selection algorithm, probably following the Channel Selection Policy
from the WiMedia Alliance when it is finalized. For now, channel 9
(BG1, TFC1) is selected.The user may override the channel selected by the radio manager and may
force the radio to stop beaconing.The WUSB Host Controller PAL makes use of this and there are two new
debug PAL commands that can be used for testing.Signed-off-by: David Vrabel

Use pre_reset and post_reset methods to avoid unbinding the radio
controller driver after a uwb_rc_reset_all() call. This avoids a
deadlock in uwb_rc_rm() when waiting for the uwb event thread to stop.Signed-off-by: David Vrabel

Use an event thread per-radio controller so processing events from one
radio controller doesn't delay another.A radio controller shouldn't have information on devices seen by a
different radio controller (they may be on different channels) so make the
beacon cache per-radio controller.Signed-off-by: Stefano Panella

ECMA-368 requires that IEs in a beacon must be sorted by element ID. Most
hardware uses the ordering in the Set IE URC command so get the ordering
right on the host.Also refactor the IE management code:
- use uwb_ie_next() instead of uwb_ie_for_each().
- remove unnecessary functions.
- API is now only uwb_rc_ie_add() and uwb_rc_ie_rm().Signed-off-by: David Vrabel
