Bluetooth: btmtk: Add MODULE_FIRMWARE() for MT7922 Since dracut refers to the module info for defining the required firmware files and btmtk driver doesn't provide the firmware info for MT7922, the generate initrd misses the firmware, resulting in the broken Bluetooth. This patch simply adds the MODULE_FIRMWARE() for the missing entry for covering that.

Bluetooth: btmtk: Add MT6639 (MT7927) Bluetooth support The MediaTek MT7927 (Filogic 380) combo WiFi 7 + BT 5.4 module uses hardware variant 0x6639 for its Bluetooth subsystem. Without this patch, the chip fails with "Unsupported hardware variant (00006639)" or hangs during firmware download. Three changes are needed to support MT6639: 1. CHIPID workaround: On some boards the BT USB MMIO register reads 0x0000 for dev_id, causing the driver to skip the 0x6639 init path. Force dev_id to 0x6639 only when the USB VID/PID matches a known MT6639 device, avoiding misdetection if a future chip also reads zero. This follows the WiFi-side pattern that uses PCI device IDs to scope the same workaround. 2. Firmware naming: MT6639 uses firmware version prefix "2_1" instead of "1_1" used by MT7925 and other variants. The firmware path is mediatek/mt7927/BT_RAM_CODE_MT6639_2_1_hdr.bin, using the mt7927 directory to match the WiFi firmware convention. The filename will likely change to use MT7927 once MediaTek submits a dedicated Linux firmware binary. 3. Section filtering: The MT6639 firmware binary contains 9 sections, but only sections with (dlmodecrctype & 0xff) == 0x01 are Bluetooth-related. Sending the remaining WiFi/other sections causes an irreversible BT subsystem hang requiring a full power cycle. This matches the Windows driver behavior observed via USB captures. Also add 0x6639 to the reset register (CONNV3) and firmware setup switch cases alongside the existing 0x7925 handling.

Bluetooth: mediatek: fix the conflict between mtk and msft vendor event There is a conflict between MediaTek wmt event and msft vendor extension logic in the core layer since 145373cb1b1f ("Bluetooth: Add framework for Microsoft vendor extension") was introduced because we changed the type of mediatek wmt event to the type of msft vendor event in the driver. But the purpose we reported mediatek event to the core layer is for the diagnostic purpose with that we are able to see the full packet trace via monitoring socket with btmon. Thus, it is harmless we keep the original type of mediatek vendor event here to avoid breaking the msft extension function especially they can be supported by Mediatek chipset like MT7921 , MT7922 devices and future devices.

Bluetooth: btusb: mediatek: add ISO data transmission functions 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.

Bluetooth: mt7921s: Support wake on bluetooth Enable wake on bluetooth on mt7921s that can be supported since the firmware with version 20211129211059 was added, and the patch would not cause any harm even when the old firmware is applied. The patch was tested by setting up an HID or HOGP profile to connect a Bluetooth keyboard and mouse, then putting the system to suspend, then trying to wake up the system by moving the Bluetooth keyboard or mouse, and then checking if the system can wake up and be brought back to the normal state.

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.

Bluetooth: btmtk: Add MT6639 (MT7927) Bluetooth support The MediaTek MT7927 (Filogic 380) combo WiFi 7 + BT 5.4 module uses hardware variant 0x6639 for its Bluetooth subsystem. Without this patch, the chip fails with "Unsupported hardware variant (00006639)" or hangs during firmware download. Three changes are needed to support MT6639: 1. CHIPID workaround: On some boards the BT USB MMIO register reads 0x0000 for dev_id, causing the driver to skip the 0x6639 init path. Force dev_id to 0x6639 only when the USB VID/PID matches a known MT6639 device, avoiding misdetection if a future chip also reads zero. This follows the WiFi-side pattern that uses PCI device IDs to scope the same workaround. 2. Firmware naming: MT6639 uses firmware version prefix "2_1" instead of "1_1" used by MT7925 and other variants. The firmware path is mediatek/mt7927/BT_RAM_CODE_MT6639_2_1_hdr.bin, using the mt7927 directory to match the WiFi firmware convention. The filename will likely change to use MT7927 once MediaTek submits a dedicated Linux firmware binary. 3. Section filtering: The MT6639 firmware binary contains 9 sections, but only sections with (dlmodecrctype & 0xff) == 0x01 are Bluetooth-related. Sending the remaining WiFi/other sections causes an irreversible BT subsystem hang requiring a full power cycle. This matches the Windows driver behavior observed via USB captures. Also add 0x6639 to the reset register (CONNV3) and firmware setup switch cases alongside the existing 0x7925 handling.

Bluetooth: btusb: mediatek: add ISO data transmission functions 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.

Bluetooth: btmtk: Add MT6639 (MT7927) Bluetooth support The MediaTek MT7927 (Filogic 380) combo WiFi 7 + BT 5.4 module uses hardware variant 0x6639 for its Bluetooth subsystem. Without this patch, the chip fails with "Unsupported hardware variant (00006639)" or hangs during firmware download. Three changes are needed to support MT6639: 1. CHIPID workaround: On some boards the BT USB MMIO register reads 0x0000 for dev_id, causing the driver to skip the 0x6639 init path. Force dev_id to 0x6639 only when the USB VID/PID matches a known MT6639 device, avoiding misdetection if a future chip also reads zero. This follows the WiFi-side pattern that uses PCI device IDs to scope the same workaround. 2. Firmware naming: MT6639 uses firmware version prefix "2_1" instead of "1_1" used by MT7925 and other variants. The firmware path is mediatek/mt7927/BT_RAM_CODE_MT6639_2_1_hdr.bin, using the mt7927 directory to match the WiFi firmware convention. The filename will likely change to use MT7927 once MediaTek submits a dedicated Linux firmware binary. 3. Section filtering: The MT6639 firmware binary contains 9 sections, but only sections with (dlmodecrctype & 0xff) == 0x01 are Bluetooth-related. Sending the remaining WiFi/other sections causes an irreversible BT subsystem hang requiring a full power cycle. This matches the Windows driver behavior observed via USB captures. Also add 0x6639 to the reset register (CONNV3) and firmware setup switch cases alongside the existing 0x7925 handling.

Bluetooth: btusb: mediatek: add ISO data transmission functions 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.
