* wl12xx: Assign value to rx msdu lifetime variableVidhya Govindan2009-07-101-0/+1
| | | | | | | | | | | The patch "wl12xx: cmd and acx interface rework" failed to assign MSDU lifetime value in wl12xx_acx_rx_msdu_life_time() and breaks the functionality. This patch fixes the regression by assigning the correct value.

* wl12xx: Fix CMD_TEST regression via netlink.Ari Kauppi2009-07-101-24/+11
| | | | | | | | | | | | | | | | | | | CMD_TEST via netlink API has been broken since e29c3f59cfbc38c3b481a2694b08962da19c4664: cmd and acx interface rework. The user of the interface sends the request in a buffer without the wl12xx_command header but expects the response to have the wl12xx_command header (with id and status). This patch reverts the e29c3f5 commit for cmd.c:wl12xx_cmd_test and implements the needed wrapper functionality in netlink.c. Now the API of wl12xx_cmd_test and rest of wl12xx_cmd_* commands in cmd.c are similar.

* wl12xx: pass the wake up condition when configuring the wake up eventLuciano Coelho2009-07-103-4/+7
| | | | | | | | | | | Changed the function wl12xx_acx_wake_up_conditions() so that it receives an argument with the actual wake up condition, instead of having WAKE_UP_EVENT_DTIM_BITMAP hardcoded. This is needed because we have to use different conditions in 1271. Signed-off-by: Luciano Coelho <luciano.coelho@nokia.com> Signed-off-by: Kalle Valo <kalle.valo@nokia.com> Signed-off-by: John W.

* wl12xx: moved firmware version reading routine to chip-specific functionsLuciano Coelho2009-07-103-3/+9
| | | | | | | | | | | With WL1271, the firmware version can only be read right after booting the chip. To keep WL1251 aligned with this procedure, the code that reads the firmware version initially has been moved to a common place where it can be read from both chipsets.

| | | | | | | | | | | In some cases we need to read more than 32 bits from the register area. These functions were added to support that, like the existing wl12xx_spi_mem_read() and wl12xx_spi_mem_write() already do for large blocks in the memory area.

* wl12xx: removed chipset interrupt source configuration from fw wakeupJuuso Oikarinen2009-07-101-2/+0
| | | | | | | | | | | | | The chipset source interrupt source configuration during fw wakeup was blocking interrupts on the wl1271. The configuration is effectively unused here as it is used to trigger an interrupt for the chipset wake-up event, which is not handled, or waited for, in the fw wakeup anyway on either wl1251 or wl1271.

| | | | | | | | | | | | | | | | | Rework cmd and acx interfaces, it was just too confusing earlier. Now all commands need to contain all the needed headers, either just cmd headers or both cmd and acx headers. This accomplish to remove the extra copy done for each command. The interfaces are now properly documented as well. Also try to make all commands safe for DMA transfers. I might have missed some, but most of them should be fixed now. And this is not all! As a free bonus you will also get some cosmetic cleanups and code reorganisation. Order today! Signed-off-by: Kalle Valo <kalle.valo@nokia.com> Signed-off-by: John W.

* wl12xx: add driverKalle Valo2009-05-0628-0/+9229
wl12xx is a driver for TI wl1251 802.11 chipset designed for embedded devices, supporting both SDIO and SPI busses. Currently the driver supports only SPI. Adding support 1253 (the 5 GHz version) should be relatively easy.
