| H A D | ar9002phy.h | diff 220590 Wed Apr 13 04:50:37 MDT 2011 adrian Port over a TX gain fix from ath9k specific to the AR9285 (Kite) and AR9271. Note: this HAL currently only supports the AR9285. From Linux ath9k: The problem is that when the attenuation is increased, the rate will start to drop from MCS7 -> MCS6, and finally will see MCS1 -> CCK_11Mbps. When the rate is changed b/w CCK and OFDM, it will use register desired_scale to calculate how much tx gain need to change. The output power with the same tx gain for CCK and OFDM modulated signals are different. This difference is constant for AR9280 but not AR9285/AR9271. It has different PA architecture a constant. So it should be calibrated against this PA characteristic. The driver has to read the calibrated values from EEPROM and set the tx power registers accordingly. |
