Unfortunately, RTL8723CS has broken BT-4.1 support, so it requires a quirk. Add a quirk and wire up 8723CS support in btrtl. I was asked for a btmon output without the quirk; however, using the chip without the quirk ends up in a bad state with "Opcode 0x c77 failed: -56" (HCI_OP_READ_SYNC_TRAIN_PARAMS) on training. A btmon output with the quirk active was already sent by Vasily. v1 of this series was sent in July 2020 by Vasily Khoruzhick. I have tested it to work on the Pinebook. Changelog: v2: * Rebase * Add uart-has-rtscts to device tree as requested by reviewer v3: * Drop the device tree as it was split out and is already integrated. * Rename the quirk as requested by reviewer Marcel Holtmann v4: * Use skb_pull_data as requested by reviewer Luiz Augusto von Dentz v5: * Make use of skb_pull_data's length check Vasily Khoruzhick (2): Bluetooth: Add new quirk for broken local ext features page 2 Bluetooth: btrtl: add support for the RTL8723CS drivers/bluetooth/btrtl.c | 120 ++++++++++++++++++++++++++++++++++-- drivers/bluetooth/btrtl.h | 5 ++ drivers/bluetooth/hci_h5.c | 4 ++ include/net/bluetooth/hci.h | 7 +++ net/bluetooth/hci_event.c | 4 +- 5 files changed, 135 insertions(+), 5 deletions(-)
