[PATCH v3 0/4] Bluetooth: btusb: MediaTek ISO data transmission

[Chris Lu <chris.lu@mediatek.com>]

Since SIG has not yet clearly defined the specification for ISO data
transmission over USB, MediaTek has adopted a method of adding an
additional interrupt endpoint for ISO data transmission. This approach
differs from the current method used in the Bluetooth upstream driver,
which utilizes existing bulk endpoints. The interrupt endpoint provides
guaranteed bandwidth, sufficient maximum data length for ISO packets
and error checking.

Certain new functions related to USB transportation, such as urb
allocation and submission, are implemented in btusb.c to leverage
existing functions and data structures defined therein. Meanwhile,
vendor-specific functions unrelated to transportation have been moved
to btmtk.c to streamline btusb.c.

Chris Lu (4):
  Bluetooth: net: add hci_iso_hdr function for iso data
  Bluetooth: btusb: add callback function in btusb suspend/resume
  Bluetooth: btmtk: add macro to get/set/clear MediaTek defined flags
  Bluetooth: btusb: mediatek: add ISO data transmission functions
