Subject: [PATCH v2 0/3] 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
