Bluetooth: HCI: Invert LE State quirk to be opt-out rather then opt-in

2024-08-15T17:07:55+00:00

This inverts the LE State quirk so by default we assume the controllers
would report valid states rather than invalid which is how quirks
normally behave, also this would result in HCI command failing it the LE
States are really broken thus exposing the controllers that are really
broken in this respect.

Bluetooth: btusb: mediatek: add ISO data transmission functions

2024-07-15T14:11:52+00:00

This patch implements functions for ISO data send and receive in btusb
driver for MediaTek's controller.

MediaTek defines a specific interrupt endpoint for ISO data transmissin
because the characteristics of interrupt endpoint are similar to the
application of ISO data which can support guaranteed transmissin
bandwidth, enough maximum data length and error checking mechanism.

Driver sets up ISO interface and endpoints in btusb_mtk_setup and clears
the setup in btusb_mtk_shutdown. These flow can't move to btmtk.c due to
btusb_driver is only defined in btusb.c when claiming/relaesing interface.
ISO packet anchor stops when driver suspending and resubmit interrupt urb
for ISO data when driver resuming.
