* wl1251: introduce wl1251_if_operations structBob Copeland2009-08-14
| | | | | | | | | | | Introduce an ops struct with read, write, and reset functions to abstract away the details of the wl1251 bus interface. Doing this will allow SDIO to coexist with SPI by supplying its own I/O routines.

* wl1251: separate bus i/o code into io.cBob Copeland2009-08-14
| | | | | | | | | | | | In order to eventually support wl1251 spi and sdio interfaces, move the register and memory transfer functions to a common file. Also rename wl1251_spi_mem_{read,write} to indicate its common usage. We still use spi_read internally until SDIO interface is introduced so nothing functional should change here.

* wl1271: add wl1271 driver filesLuciano Coelho2009-08-14
| | | | | | | | | | | | | | 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.

* mac80211: push rx status into skb->cbJohannes Berg2009-07-10
| | | | | | | | | | | | | | | Within mac80211, we often need to copy the rx status into skb->cb. This is wasteful, as drivers could be building it in there to start with. This patch changes the API so that drivers are expected to pass the RX status in skb->cb, now accessible as IEEE80211_SKB_RXCB(skb). It also updates all drivers to pass the rx status in there, but only by making them memcpy() it into place before the call to the receive function (ieee80211_rx(_irqsafe)). Each driver can now be optimised on its own schedule. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

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.
