Looking for out-of-tree modem driver

[Oli]

Hi, I'm looking to develop an out-of-tree driver for the SIM800L modem. The reason I want to develop it out of tree is that I don't believe have the skills or resources to do a proper in-tree driver that is thoroughly tested and documented. It would help me greatly to get started if I could find an existing out-of-tree driver repository (preferably a modem) with the correct file structure so I can start coding more rapidly. Otherwise, any resource to help me get started would be appreciated.

Just found this repository which contains an out-of-tree sensor driver: https://github.com/zephyrproject-rtos/example-application/tree/main

An out-of-tree modem driver would be even better but it seems like a good starting point.

I am not aware of any here so I would recommend you to ask on a few other forums as well but the out of tree sensor drives is likely a ok starting point.
