The firmware upload question is being tracked separately in linux-firmware MR !946. On that topic - would it be possible for MediaTek to provide a proper BT firmware binary for linux-firmware, or to sign off on the one extracted from the ASUS driver package? That would resolve the firmware provenance concern. If a formal submission from MediaTek is required, could you help coordinate that? > This is common logic for the other mediatek chips.

The BTMTK_FIRMWARE_LOADED flag and skip logic are removed in v2. Firmware persistence is handled by the existing framework as you suggested. v2 is sent with these changes addressed. Best, Javier
