Subject: wl12xx: driver for TI wl1251 chipset
Date: Tue, 10 Feb 2009 12:32:04 +0200 [thread overview]
Message-ID: <87iqnishuj.fsf@nokia.com> (raw)
Hello all,
in Nokia we have been working on a mac80211 driver for TI wl1251
chipset. We named it as wl12xx, and in the future we are planning to
add wl1271 support to the driver as well.
wl1251 is a chipset 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. More information here:
http://focus.ti.com/general/docs/wtbu/wtbuproductcontent.tsp?contentId=4711&navigationId=12494&templateId=6123
Because the patch is over 200 KB, the driver is temporarily available
from my server:
http://www.valot.fi/kalle/tmp/wl12xx/wl12xx-2.6.28-1.patch
The patch is against linux-2.6.28-omap1 tag available here:
http://git.kernel.org/?p=linux/kernel/git/tmlind/linux-omap-2.6.git;a=commit;h=0ec95b96fd77036a13398c66901e11cd301190d0
Currently known issues:
o short slot and preamble support missing
o rts/cts and cts-to-self missing
o no proper bitrate control support
o using deprecated omap_get_config(), need to convert to use platform_data
o firmware wakeup not working, deepest sleep state in firmware not yet
enabled
Also the driver has a netlink interface which is used for running
production line tests and pushing the calibration data from user
space.
All comments and review is greatly appreciated. After receiving all
the comments, I will port the driver to the wireless-testing tree and
submit a version for the possible inclusion.
TI has given us technical support while developing the driver, big
thanks to them.
