2011-01-04carl9170: reduce channel change delayChristian Lamparter1-8/+0
By removing two "safety" msleeps (and an echo nop), the channel change delay is effectively halved. Previously, the delay could be as long as 260 ms and the device could not go off-channel without risking to miss the next DTIM beacon [interval ~307 ms].

2011-01-04carl9170: add missing return-value checkChristian Lamparter1-0/+2
This patch adds a forgotten bail-out path. Signed-off-by: Christian Lamparter <chunkeey@googlemail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-11-15carl9170: use generic sign_extend32Christian Lamparter1-13/+4
This patch replaces the handcrafted sign extension cruft with a generic bitop function. Signed-off-by: Christian Lamparter <chunkeey@googlemail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-09-21carl9170: reinit phy after HT settings have changedChristian Lamparter1-12/+13
The driver has a set of different initvals for 20 MHz vs dynamic HT2040 operation. Because we can't change some of the registers "in-flight", the driver needs to perform a warm reset.

2010-09-21carl9170: don't load bogus nf of chain 1Christian Lamparter1-6/+5
According to Atheros, chain 1 is not connected. Signed-off-by: Christian Lamparter <chunkeey@googlemail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-09-21carl9170: fix noise dBm conversionChristian Lamparter1-2/+2
Ever since carl9170 gained support to read the noisefloor, the reported noisefloor level was pretty poor. Initially I assumed that something was wrong in the PHY setup and it would be impossible to fix without any guidances. But this was not the case. In fact the nf readings were correct and the thing that was broken was the "simple" sign extension code! Signed-off-by: Christian Lamparter <chunkeey@googlemail.com> Signed-off-by: John W.

2010-09-21carl9170: use rx chainmask from eepromChristian Lamparter1-1/+4
The eeprom provides a mask for all present rx chains. Why not use it instead of the generic initval default? Signed-off-by: Christian Lamparter <chunkeey@googlemail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-09-21carl9170: update AR9170 phy initvalsChristian Lamparter1-3/+5
This patch is loosely based on an ath9k patch called: "ath9k_hw: sync initvals for ar9001 and ar9002 with Atheros" It includes the following changes/fixes: - AGC setting improvements - timing changes for improved performance Signed-off-by: Christian Lamparter <chunkeey@googlemail.com> Signed-off-by: John W.
