2016-10-07ath9k: Fix programming of minCCA power thresholdSven Eckelmann1-1/+1
commit aaab50fcea78ae3414c3afc25aae8d0603df34d0 upstream. The function ar9003_hw_apply_minccapwr_thresh takes as second parameter not a pointer to the channel but a boolean value describing whether the channel is 2.4GHz or not. This broke (according to the origin commit) the ETSI regulatory compliance on 5GHz channels.

2014-11-25ath9k: add TX power per-rate tablesLorenzo Bianconi1-0/+47
Add TX power per-rate tables for different MIMO modes (e.g STBC) in order to cap the maximum TX power value per-rate in the TX descriptor path. Cap TX power for self generated frames (ACK, RTS/CTS).

2012-12-11ath9k: use 'struct ath_hw *' as the first argument for 'ath9k_hw_nvram_read'Gabor Juhos1-9/+8
The 'ath9k_hw_nvram_read' function takes a 'struct ath_common *' as its first argument. Almost each of its caller has a 'struct ath_hw *' parameter in their argument list, and that is dereferenced in order to get the 'struct ath_common' pointer. Change the first argument of 'ath9k_hw_nvram_read' to be a 'struct ath_hw *', and remove the dereference calls from the callers.

2012-10-29ath9k: adjust WLAN and BT concurrent transmissionRajkumar Manoharan1-3/+15
The simulataneous transmission of both WLAN and BT might cause increase in power levels. To avoid regulatory violation, WLAN tx power will be adjusted according to BT power index based on avaliability of BT scheduling messages. WLAN tx power reduction might affect its performance. So WLAN tx power is only be lowered when the signal strength is good enough. Otherwise concurrent tx will be disabled and WLAN uses it default power levels. Also concurrent tx is disabled whenever WLAN is moving to off-channel which might be used by BT. Signed-off-by: Rajkumar Manoharan <rmanohar@qca.qualcomm.com> Signed-off-by: John W.
