+Subject: [PATCH] ath9k: Fix BTCOEX weight initialization
+
+The WLAN/BT weights have to set correctly before BTCOEX
+is initialized. Currently, this is not done for all chips
+in the AR9003 family. This patch fixes this issue by setting
+the weights in the init path. While at it, rename ar9462_wlan_weights
+to mci_wlan_weights since it is common to both AR9462 and AR9565.

+Self generated MCI messages is configured to use chain 1. As

+Chain 1 for ar9462 alone. Not doing so, could affect WLAN

+Subject: [PATCH 06/11] ath9k_hw: Fix frequent BT rx recovery
+
+While resuming from S3, BT host issues HCI reset command and it
+causes BT firmware to busy with security key calculation. At this
+movement, WLAN detects MCI hardware error of MCI_CONT_INFO_TIMEOUT
+and then it starts the recovery sequence repeatedly. Too many
+recovery sequences would exhaust the BT kernel message pool. This
+patch imposes a duration between consecutive BT recovery procedure.
+Thus it solves BT firmware panic issue reported in AR9565.
