2012-05-29wlcore: fix undefined symbols when CONFIG_PM is not definedEyal Shapira3-1/+7
commit c21eebb50379a96e1335e933583dcd5b455c6b64 "wl12xx: add RX filters ACX commands" breaks the build when CONFIG_PM isn't defined: ERROR: "wl1271_rx_filter_get_fields_size" [drivers/net/wireless/ti/wlcore/wlcore.ko] undefined! ERROR: "wl1271_rx_filter_flatten_fields" [drivers/net/wireless/ti/wlcore/wlcore.ko] undefined! code in drivers/net/wireless/ti/wlcore/acx.c is using these functions unconditionally while they are #ifdefed CONFIG_PM. Fix it by ifdefing all relevant RX filters code with CONFIG_PM.

2012-05-25wl1251: fix oops on early interruptGrazvydas Ignotas2-3/+2
This driver disables interrupt just after requesting it and enables it later, after interface is up. However currently there is a time window between request_irq() and disable_irq() where if interrupt arrives, the driver oopses because it's not yet ready to process it. This can be reproduced by inserting the module, associating and removing the module multiple times. Eliminate this race by setting IRQF_NOAUTOEN flag before request_irq().

2012-04-12wlcore/wl12xx: use a single memory config and reset if using wl127xLuciano Coelho4-17/+41
Instead of having two memory configuration sets, one for wl127x and one for wl128x, we can use only one which should be correctly set by the lower driver.

2012-04-12wlcore/wl12xx: turn no-Tx-align quirk into Tx-alignArik Nemtsov5-12/+15
Inverting the quirk flag to indicate Tx-alignment. This aligns it with the similar Rx-side quirk. The call to wl1271_set_block_size() decides whether SDIO block size alignment can be used or not. In case we're using SPI, we can't use the block size alignment, so the function returns false. So we set the quirk when wl1271_set_block_size() returns true and let the wl12xx lower driver unset the bit for wl127x (since it doesn't support this quirk).

2012-04-12wlcore/wl12xx: split Tx completion to immediate/delayedArik Nemtsov5-3/+30
One chip family employs immediate Tx completion, where knowledge of completed packets is given as part of the FW status. Another is only notified of Tx completion via the FW status, and has to read the completion status of the packets from a different location.

The only difference in the read_data operations is that some chips need to prepare the data to be read before reading. So instead of having a mandatory read_data operation, we now have an option prepare_data operation that only needs to be implemented for chips that require it.
