Sujith Manoharan 4cfe9a8d58 ath9k: Fix TX power calculation
The commit, "ath9k_hw: Fix incorrect Tx control power in AR9003 template"
fixed the incorrect values in the eeprom templates, but if
boards have already been calibrated with incorrect values,
they would still be using the wrong TX power. Fix this by assigning
a default value in such cases.

Whenever the return value of snprintf() is used to calculate

Gabor Juhos 0e4b9f2f12 ath9k: use 'struct ath_hw *' as the first argument for 'ath9k_hw_nvram_read'
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.

Also change the type of the first argument of the
ar9300_eeprom_read_{byte,word} functions.

Rajkumar Manoharan e82cb03f5a ath9k: adjust WLAN and BT concurrent transmission
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.
