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