This driver supports the wl1271 chipset from Texas Instruments based on the WiLink(tm) 6.0 mobile platform. Support for wl1273 should be relatively easy to add. This chipset is designed for embedded devices, with good powersaving capabilities. The wl1271 chipset is the successor of wl1251 and supports the 802.11b/g/n standards, but currently this driver supports only b/g. More information about this chipset can be found here: http://focus.ti.com/general/docs/wtbu/wtbuproductcontent.tsp?templateId=6123&navigationId=12762&contentId=29993 Signed-off-by: Luciano Coelho <luciano.coelho@nokia.com> Signed-off-by: John W.

* Mbox events
|
|

|
|
* The event mechanism is based on a pair of event buffers (buffers A and
|
|
* B) at fixed locations in the target's memory. The host processes one
|
|
* buffer while the other buffer continues to collect events. If the host
|
|
* is not processing events, an interrupt is issued to signal that a buffer
|
|
* is ready. Once the host is done with processing events from one buffer,
|
|
* it signals the target (with an ACK interrupt) that the event buffer is
|
|
* free.
