+Subject: [PATCH] wifi: ath11k: Add HTT stats for PHY reset case
+
+New HTT stats are added with stats type 37 to
+provide PHY reset stats and PHY reset counter stats.
+
+PHY reset stats are used to display the current
+PHY-related operation information such as band, CCA
+threshold, current operating channel etc.,
+
+PHY reset counter stats are used to display the
+PHY reset counter values like calibration counts,
+temperature based recalibration counts etc.,
+
+Usage:
+echo 37 > /sys/kernel/debug/ieee80211/phyX/ath11k/htt_stats_type
+cat /sys/kernel/debug/ieee80211/phyx/ath11k/htt_stats
