Description:
Interfaces for WiMedia Ultra Wideband Common Radio
Platform (UWB) radio controllers.
Familiarity with the ECMA-368 'High Rate Ultra
Wideband MAC and PHY Specification' is assumed.

Date: July 2008
KernelVersion: 2.6.27
Description:
If no beacons are received from a device for at least
this time, the device will be considered to have gone
and it will be removed. The default is 3 superframes
(~197 ms) as required by the specification.

Write:
uwb: add basic radio manager 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 <david.vrabel@csr.com>

to force a specific channel to be used when beaconing,
or, if <channel> is -1, to prohibit beaconing. If
<channel> is 0, then the default channel selection
algorithm will be used. Valid channels depends on the
radio controller's supported band groups.

the radio controller is not beaconing.
