 t7xx driver for MTK PCIe based T700 5G modem
 ============================================
-The t7xx driver is a WWAN PCIe host driver developed for linux or Chrome OS platforms
-for data exchange over PCIe interface between Host platform & MediaTek's T700 5G modem.
-The driver exposes an interface conforming to the MBIM protocol [1]. Any front end
-application (e.g. Modem Manager) could easily manage the MBIM interface to enable
-data communication towards WWAN. The driver also provides an interface to interact
-with the MediaTek's modem via AT commands.
