It requires different firmware files and has different current requirements, so add it as a separate SoC type. The firmware for these chips has been recently added to the linux-firmware repository and will be a part of the upcoming release: - qca/cmbtfw12.tlv - qca/cmbtfw13.tlv - qca/cmnv12.bin - qca/cmnv13.bin - qca/cmnv13s.bin - qca/cmnv13t.bin Signed-off-by: Dmitry Baryshkov Signed-off-by: Luiz Augusto von Dentz Signed-off-by: Sasha Levin --- drivers/bluetooth/btqca.c | 14 ++++++++++++++ drivers/bluetooth/btqca.h | 4 ++++ drivers/bluetooth/hci_qca.c | 25 +++++++++++++++++++++++++ 3 files changed, 43 insertions(+) diff --git a/drivers/bluetooth/btqca.c b/drivers/bluetooth/btqca.c index 7d6b02fe2040f..3d6778b95e005 100644 --- a/drivers/bluetooth/btqca.c +++ b/drivers/bluetooth/btqca.c @@ -816,6 +816,10 @@ int qca_uart_setup(struct hci_dev *hdev, uint8_t baudrate, snprintf(config.fwname, sizeof(config.fwname), "qca/%s", rampatch_name);
