2024-08-21	net: wwan: t7xx: PCIe reset rescan	Jinjian Song
	WWAN device is programmed to boot in normal mode or fastboot mode, when triggering a device reset through ACPI call or fastboot switch command. Maintain state machine synchronization and reprobe logic after a device reset. The PCIe device reset triggered by several ways. E.g.: - fastboot: echo "fastboot_switching" > /sys/bus/pci/devices/${bdf}/t7xx_mode. - reset: echo "reset" > /sys/bus/pci/devices/${bdf}/t7xx_mode. - IRQ: PCIe device request driver to reset itself by an interrupt request. Use pci_reset_function() as a generic way to reset device, save and restore the PCIe configuration before and after reset device to ensure the reprobe process.

2022-11-02	net: wwan: t7xx: Add port for modem logging	M Chetan Kumar
	The Modem Logging (MDL) port provides an interface to collect modem logs for debugging purposes. MDL is supported by the relay interface, and the mtk_t7xx port infrastructure. MDL allows user-space apps to control logging via mbim command and to collect logs via the relay interface, while port infrastructure facilitates communication between the driver and the modem.
