Bluetooth: btrtl: Add the support for RTL8851B

2023-05-24T16:30:08+00:00

[ Upstream commit 7948fe1c92d92313eea5453f83deb7f0141355e8 ] 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.

Bluetooth: btrtl: check for NULL in btrtl_set_quirks()

2023-05-24T16:30:08+00:00

[ Upstream commit 253cf30e8d3d001850a95c4729d668f916b037ab ] The btrtl_set_quirks() has accessed btrtl_dev->ic_info->lmp_subver since b8e482d02513. However, if installing a Realtek Bluetooth controller without the driver supported, it will hit the NULL point accessed. Add a check for NULL to avoid the Kernel Oops.

Bluetooth: btrtl: add support for the RTL8723CS

2023-05-24T16:30:07+00:00

[ Upstream commit c0123cb6c4c7fc2a42ead6cd7d3e82b8e1c25c6f ] The Realtek RTL8723CS is a SDIO WiFi chip. It also contains a Bluetooth module which is connected via UART to the host. It shares lmp subversion with 8703B, so Realtek's userspace initialization tool (rtk_hciattach) differentiates varieties of RTL8723CS (CG, VF, XX) with RTL8703B using vendor's command to read chip type. Also this chip declares support for some features it doesn't support so add a quirk to indicate that these features are broken.

Bluetooth: btusb: Ignore zero length of USB packets on ALT 6 for specific chip

2022-12-12T22:19:23+00:00

For USB ALT 6 settings some Realtek chips need to transmit mSBC data continuously without the zero length of USB packets. In this commit, create BTUSB_ALT6_CONTINUOUS_TX to manage the behavior. Therefore, create REALTEK_ALT6_CONTINUOUS_TX_CHIP to manage the specific chip model for the behavior. Signed-off-by: Max Chou Signed-off-by: Hilda Wu Signed-off-by: Luiz Augusto von Dentz

Bluetooth: btrtl: Ask ic_info to drop firmware

2021-10-01T09:40:47+00:00

Some un-support wakeup platforms keep USB power and suspend signal is coming late, this makes Realtek some chip keep its firmware, and make it never load new firmware. So use vendor specific HCI command to ask them drop its firmware after system shutdown or resume. Signed-off-by: Hilda Wu Signed-off-by: Marcel Holtmann
