Subject: [PATCH 0/4] wifi: rtw89: coex: fine tune free-run policy and update debug counters

Main update related to 8851B is patch 4/4 that sends more information to
firmware via H2C command, which converts to suggested format as well.
Other patches are to update things found during developing BT-coexistence
mechanism for 8851B.

Ching-Te Ku (3):
wifi: rtw89: coex: Enable Wi-Fi RX gain control for free run solution
wifi: rtw89: coex: Add path control register to monitor list
wifi: rtw89: coex: Update function to get BT RSSI and hardware counter

Subject: [PATCH 2/4] wifi: rtw89: coex: Add path control register to monitor list

From: Ching-Te Ku <[email protected]>

Chips use similar hardware for path control, but could different
path/antenna configuration. Add these register to monitor, if there are
wrong settings, these register can help to debug.

Subject: [PATCH 4/4] wifi: rtw89: coex: send more hardware module info to firmware for 8851B

8851B has various hardware module types, so BT coexistence in firmware
needs these information to make decision. Add them to make 8851B work
well.
