Bluetooth: btusb: MediaTek ISO data transmission support

|
Since SIG hasn't clearly defined the specification about ISO data over USB transmission yet, MediaTek adopts a method by adding an additional interrupt endpoint for ISO data transmission which is different from current way on Bluetooth upstream driver using existed bulk. Interrupt endpoint has guaranteed bandwidth, sufficient max data length for LE audio packet and support error checking. These characteristics are similar to the use of ISO data. --- Change in v2: -Fix warning report from bluez.test.bot in btusb.c, align with other packet type to parsing dlen when getting iso data. --- Chris Lu (3): Bluetooth: net: add hci_iso_hdr function for iso data Bluetooth: btmtk: add macro to get/set/clear MediaTek defined flags Bluetooth: btusb: mediatek: add MediaTek ISO data transmission function drivers/bluetooth/btmtk.c | 35 +++++ drivers/bluetooth/btmtk.h | 46 ++++++ drivers/bluetooth/btusb.c | 295 +++++++++++++++++++++++++++++++++++- include/net/bluetooth/hci.h | 5 + 4 files changed, 380 insertions(+), 1 deletion(-)
