Add support for userspace to enable/disable the debug ports(ADB,MIPC).
- ADB port: /dev/wwan0adb0
- MIPC port: /dev/wwan0mipc0
Application can use ADB (Android Debug Bridge) port to implement
functions (shell, pull, push ...) by ADB protocol commands.
E.g., ADB commands:
- A_OPEN: OPEN(local-id, 0, "destination")
- A_WRTE: WRITE(local-id, remote-id, "data")
- A_OKEY: READY(local-id, remote-id, "")
- A_CLSE: CLOSE(local-id, remote-id, "")
Link: https://android.googlesource.com/platform/packages/modules/adb/+/refs/heads/main/README.md
Application can use MIPC (Modem Information Process Center) port
to debug antenna tuner or noise profiling through this MTK modem
diagnostic interface.
By default, debug ports are not exposed, so using the command
to enable or disable debug ports.
Enable debug ports:
- enable: 'echo 1 > /sys/bus/pci/devices/${bdf}/t7xx_debug_ports
Disable debug ports:
- disable: 'echo 0 > /sys/bus/pci/devices/${bdf}/t7xx_debug_ports

On early detection of wwan device in fastboot mode, driver sets
up CLDMA0 HW tx/rx queues for raw data transfer and then create
fastboot port to userspace.
Application can use this port to flash firmware and collect
core dump by fastboot protocol commands.
E.g., flash firmware through fastboot port:
- "download:%08x": write data to memory with the download size.
- "flash:%s": write the previously downloaded image to the named partition.
- "reboot": reboot the device.

Add support for userspace to get/set the device mode, device's state
machine changes between (unknown/ready/reset/fastboot).
Get the device state mode:
- 'cat /sys/bus/pci/devices/${bdf}/t7xx_mode'
Set the device state mode:
- reset(cold reset): 'echo reset > /sys/bus/pci/devices/${bdf}/t7xx_mode'
- fastboot: 'echo fastboot_switching > /sys/bus/pci/devices/${bdf}/t7xx_mode'
Reload driver to get the new device state after setting operation.
