Subject: [PATCH] Bluetooth: btusb: Add debugfs to force toggling remote wakeup
Date: Mon, 22 Apr 2024 15:25:01 +0800 [thread overview]
Message-ID: <20240422152500.1.I8939e49084a6fef78496eb73edafdf3c2c4afbf4@changeid> (raw)
From: Archie Pusaka <apusaka@chromium.org>
Sometimes we want the controller to not wake the host up, e.g. to
save the battery. Add some debugfs knobs to force the wake by BT
behavior.
