* wl1271: Change wl12xx Files NamesShahar Levi2010-11-221-178/+0
| | | | | | | | | All files name prefix removed due to the fact that wl12xx driver supports wl1271 and wl1273. Also the definition in Kconfig and header files changed respectively. Signed-off-by: Shahar Levi <shahar_levi@ti.com> Signed-off-by: Luciano Coelho <luciano.coelho@nokia.com>
* wl1271: Add hardware recovery mechanismJuuso Oikarinen2010-09-281-1/+2
| | | | | | | | | | There is some probability of hardware failures, which currently go largely undetected. Attempt to recover from these failures by shutting down the hardware, and requesting mac80211 to reconfigure it.

* wl1271: Fix work cancelling when shutting down the driverJuuso Oikarinen2010-09-281-0/+3
| | | | | | | | | | | | The work cancelling has had several hazards, ranging from potentially executing work after the driver is in OFF state, to executing work after the driver and relevant memory structures are already removed. Fix these. Signed-off-by: Juuso Oikarinen <juuso.oikarinen@nokia.com> Reviewed-by: Teemu Paasikivi <ext-teemu.3.paasikivi@nokia.com> Signed-off-by: Luciano Coelho <luciano.coelho@nokia.com>

* wl1271: Move setting of wake-up conditions to ps.c from cmd.cJuuso Oikarinen2010-09-281-0/+6
| | | | | | | | | This removes a fixme. Also, it removes a redundant setting of the wake-up conditions when exiting power save mode, which should improve performance.

* wl1271: Fix PSM entryJuuso Oikarinen2010-02-191-17/+4
| | | | | | | | | | | | | | Currently the PSM entry function assumes successful operation, and enables ELP, BET and beacon filtering right away. This is bad, because the PSM entry may fail due to environmental issues, which will cause the ELP, BET and beacon filtering to be illegally enabled (because FW remains in active state.) Fix this by enabling ELP, BET and beacon filtering only after successful entry, and by ensuring the firmware is in active mode after the failure.

* wl1271: add wl1271 driver filesLuciano Coelho2009-08-141-0/+142
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.
