This module adds support for wireless adapters based on TI wl1271,
wl1273, wl1281 and wl1283 chipsets. This module does *not* include
support for wl1251. For wl1251 support, use the separate homonymous
driver instead.

This module contains the main code for TI WLAN chips. It abstracts

---help---
This will enable TI wl12xx driver support for the following chips:
wl1271, wl1273, wl1281 and wl1283.
The drivers make use of the mac80211 stack.
config WL12XX
tristate "TI wl12xx support"

---help---
This module adds support for wireless adapters based on TI wl1271 and
TI wl1273 chipsets. This module does *not* include support for wl1251.
For wl1251 support, use the separate homonymous driver instead.
If you choose to build a module, it will be called wl12xx. Say N if
unsure.

This module adds support for the SPI interface of adapters using
TI wl12xx chipsets. Select this if your platform is using
the SPI bus.
If you choose to build a module, it'll be called wl12xx_spi.
Say N if unsure.

This module adds support for the SDIO interface of adapters using
TI wl12xx chipsets. Select this if your platform is using
