ath9k_hw: make sure PAPRD training is properly done
checking the status of PAPRD_AGC2_POWER(Log(ADC_power) measured after last gain-change in dB) field suggests whether the PAPRD is completely/properly done. This is an additional check apart from polling for PAPRD done bit being set. Susinder suggests that the ideal power range value should be 0xf0 to 0xfe. With AR9382 we do have the values in this range. to have a common check for all platforms we take agc2_power should be atleast greater than 0xe0 Cc: susinder@qca.qualcomm.com Cc: senthilb@qca.qualcomm.com Cc: kmuthusa@qca.qualcomm.com Signed-off-by: Mohammed Shafi Shajakhan <mohammed@qca.qualcomm.com> Signed-off-by: John W.
