Subject: [PATCH] Bluetooth: btrtl: Add the support for RTL8851B
From: Max Chou <max.chou@...ltek.com>
Add the support for RTL8851B BT controller on USB interface.
The necessary firmware will be submitted to linux-firmware project.
Note that the Bluetooth devices WITH the VID=0x0bda would be set the
feature quirk in btrtl_setup_realtek(). It's able to ignore the
feature flag set for the specific VID and PID in blacklist_table[] of
btusb.c. (check [1])
If Realtek Bluetooth chips WITHOUT the VID=0x0bda, it shall be added
the feature flag for the specific VID and PID in blacklist_table[] of
btusb.c. (check [2])
[1] '9ab9235fe5cf ("Bluetooth: btrtl: Enable WBS for the specific
Realtek devices")'
[2] '73280f13c9bb ("Bluetooth: btusb: Add the more support IDs for
Realtek RTL8822CE")'
The device info from /sys/kernel/debug/usb/devices as below.
