Currently in ath9k code there is an attempt which is meant to disable ANI for 
ar9100 and ar9340. But it doesn't really achieve this. All it does is disable 
ANI init and setup (i.e. calls to ath9k_hw_ani_setup and ath9k_hw_ani_init). 
Since ath9k_hw_ani_setup is not called ah->config.ani_poll_interval is never 
initialized (i.e. it is always zero) and ath_ani_calibrate always executes ANI 
procedures (over uninitialized ANI parameters).
  Moreover, ath_ani_calibrate is being called each 1ms because 
common->ani.timer is set to zero interval because 
ah->config.ani_poll_interval==0 (and thus smallest value of all intervals). 
Normally it should not be called this often.
  This patchset makes use of config.enable_ani to check if ANI should be 
performed. It sets config.enable_ani to false for appropriate platforms.
  Also last patch in this set enables ANI for ar9100 - it seems to be working 
fine there (tested on ar9102).

  Question: there are common.disable_ani (and corresponding debugfs file) and 
config.enable_ani in ath9k code. config.enable_ani sets if ANI is supported and 
common.disable_ani is meant to disable calibration. This is confusing on a 
sense that disable_ani completely disables all calibration code including 
short/long calibration and ANI, not ANI alone. Would it make sense to rename 
disable_ani to disable_calib and enable_ani to ani_supported?

  All comments and suggestions are appreciated.
  Thanks.
