net: wwan: t7xx: Add debug ports
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
