wl1271: add wl1271 driver files 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.

wl1271: Work around AP's with broken ps-poll functionality Some AP's (such as Zyxel Prestige 600) have totally broken ps-poll functionality. When powersave is enabled, these AP's will set the TIM bit for a STA in beacons, but when the STA responds with a ps-poll, the AP does not respond with data. The wl1271 firmware is able to send an indication to the host, when this problem occurs. This patch adds implementation, which temporarily disables power-save in response to this indication, allowing the AP to transmit whatever data it has buffered for the STA / whatever data is inbound at that time. This patch does not make these AP's work reliably in PSM, but improves the chances of inbound data getting through. The side effect of this patch is increased power consumption when using a faulty AP.

wl12xx: rearrange some ELP wake_up/sleep calls ELP (Extremely/Enhanced Low Power, or something like that ;)) refers to the powerstate of the 12xx chip, in which very low power is consumed, and no commands (from the host) can be issued until the chip is woken up. Wakeup/sleep commands must be protected by a wl->mutex, so it's generally a good idea to call wakeup/sleep along with the mutex lock/unlock (where needed). However, in some places the wl12xx driver calls wakeup/sleep in some "inner" functions. This result in some "nested" wakeup/sleep calls which might end up letting the chip go to sleep prematurely (e.g. during event handling). Fix it by rearranging the elp calls to come along with mutex_lock/unlock.

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: fix endianess issues We were not handling endianess correctly. The wl1271 chip runs on little-endian values. This patch makes sure that all the communication with the wl1271 firmware is done in little-endian by using cpu_to_le* and le*_to_cpu where appropriate. Also, all the struct definitions for data exchanged with the firmware has been changed to use __le16/32 types instead of u16/32.

The wl1271 firmware doesn't allow these sets to be mixed, so up to several scan commands have to be issued. This patch also allows scanning more than 24 channels per set, by breaking the sets into smaller parts if needed (the firmware can scan a maximum of 24 channels at a time). Previously, the scanning code was erroneously scanning all channels possible actively, not complying with the CRDA values. This is also fixed with this patch.

wl1271: Work around AP's with broken ps-poll functionality Some AP's (such as Zyxel Prestige 600) have totally broken ps-poll functionality. When powersave is enabled, these AP's will set the TIM bit for a STA in beacons, but when the STA responds with a ps-poll, the AP does not respond with data. The wl1271 firmware is able to send an indication to the host, when this problem occurs. This patch adds implementation, which temporarily disables power-save in response to this indication, allowing the AP to transmit whatever data it has buffered for the STA / whatever data is inbound at that time. This patch does not make these AP's work reliably in PSM, but improves the chances of inbound data getting through. The side effect of this patch is increased power consumption when using a faulty AP.

wl12xx: 1281/1283 support - Add dummy packet support Support sending dummy packet to wl128x FW as results of dummy packet event. That is part of dynamic TX mem blocks mechanism. Only send dummy packet when not in AP mode. [Even though the DUMMY_PACKET_EVENT_ID and the STA_REMOVE_COMPLETE_EVENT_ID events are defined to the same value, we need to treat them separately in the code. Keep the check and enable STA_REMOVE_COMPLETE_EVENT_ID for AP mode and DUMMY_PACKET_EVENT_ID for STA. Moved one warning to a cleaner place.
