This driver is required for the functioning of Quectel EM05 and EM12 etc... modems present on the Rock 5B+ / Rock 5T . The driver is present in both JoshuaRieks/linux-rockchip (https://github.com/Joshua-Riek/linux-rockchip/tree/noble/drivers/net/lte) and Radxa/kernel (https://github.com/radxa/kernel/tree/linux-6.1-stan-rkr5.1/drivers/net/lte) .
I have tested the image with this driver enabled (CONFIG_LTE=y , CONFIG_LTE_EM05=y) and it works and detects the Quectel EM12 card on the Rock 5T:
Bus 003 Device 005: ID 2c7c:0512 Quectel Wireless Solutions Co. , Ltd. EM12-G
Once this driver is added to the kernel source here, we can request a change in armbian/build/config/kernel/linux-rk35xx-vendor to enable the required config flags.
