   4 Subject: [PATCH] ath: add support to get the detected radar specifications
   5
   6 This enables ath10k/ath9k drivers to collect the specifications of the
   7 radar type once it is detected by the dfs pattern detector unit.
   8 Usage of the collected info is specific to driver implementation.
   9 For example, collected radar info could be used by the host driver
  10 to send to co-processors for additional processing/validation.
  11
  12 Note: 'radar_detector_specs' data containing the specifications of
  13 different radar types which was private within dfs_pattern_detector/
  14 dfs_pri_detector is now shared with drivers as well for making use
  15 of this information.
