2011-07-11ath9k_hw: add a missing delay for an analog registerFelix Fietkau
AR_AN_SYNTH9 is in the analog shift register range and thus needs to be written using the ath9k_hw_analog_shift_rmw function. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-07-11ath9k_hw: set 5 GHz half/quarter channels on AR9002 using fractional modeFelix Fietkau

2011-07-11ath9k_hw: remove hardcoded PLL overrides for AR9280Felix Fietkau

2011-05-16ath9k_hw: define antenna diversity groupMohammed Shafi Shajakhan
AR9285 belongs to diversity group 0 and AR9485 belongs to diversity group 2. Based on the diversity group we configure certain antenna diversity paramaters such as lna1_lna2_delta and fast diversity bias values. For AR9485 we have some gain table parameter which selects the gain table 0/1 for main and alternate antenna Cc: Gabriel Tseng <Gabriel.Tseng@Atheros.com> Cc: Senthilkumar Balasubramanian <Senthilkumar.Balasubramanian@Atheros.com> Signed-off-by: Mohammed Shafi Shajakhan <mshajakhan@atheros.com> Signed-off-by: John W.

2011-01-04ath9k: fix spur mitigation no-spur case for AR9002Brian Prodoehl
For the AR9002, the spur frequency read from the EEPROM is mangled before being compared against AR_NO_SPUR. This results in the driver trying to set up the spur mitigation for bogus spurs, rather than cleanly breaking out. Signed-off-by: Brian Prodoehl <bprodoehl@nomadio.net> Signed-off-by: John W.

2010-11-15bitops: Provide generic sign_extend32 functionAndreas Herrmann
This patch moves code out from wireless drivers where two different functions are defined in three code locations for the same purpose and provides a common function to sign extend a 32-bit value.

2010-10-06ath9k_hw: clean up register write bufferingFelix Fietkau
Throughout the code, DISABLE_REGWRITE_BUFFER is always called right after REGWRITE_BUFFER_FLUSH. Since that's unlikely to change any time soon, that makes keeping those ops separate rather pointless, as it only increases code size and line number counts.

2010-07-26ath9k_hw: fix invalid extension channel noisefloor readings in HT20Felix Fietkau
When the hardware is configured in HT20 mode, noise floor readings for the extension channel often return invalid values, which keep the values in the NF history buffer at the hardware-specific maximum limit. Fix this by discarding the extension channel values when in HT20 mode. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2010-04-16ath9k_hw: Use buffered register writesSujith

2010-04-16ath9k_hw: add a private callback for PLL control computationLuis R. Rodriguez
The PLL control computation used to program the AR_RTC_PLL_CONTROL register varies between our harware so just add a private callback for it. AR9003 will use its own callback. Signed-off-by: Luis R. Rodriguez <lrodriguez@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-04-16ath9k_hw: Move some RF ops to the private callbacksLuis R. Rodriguez
The PHY split is easier done in a few steps. First move the RF ops to the private ops and rename them accordingly. We split PHY stuff up first for the AR5008 and AR9002 families. There are some callbacks that AR9002 share with the AR5008 familiy so we set those first, if AR9002 has some different callbacks it will override them upon hardware init.
