Subject: [PATCH] rtw88: coex: add power off setting
Date: Fri, 19 Feb 2021 13:41:40 +0800 [thread overview]
Message-ID: <20210219054140.7835-1-pkshih@realtek.com> (raw)
Clear WL/BT on/off bit in scoreboard register that is used to exchange
WL/BT status. Since the status is preserved after warm reboot, we must
clear it when WL is going to down.
