How to include sierra wireless drivers into a yocto build for EM9191 and EM9291 devices

I assume there must be some documentation somewhere that I am missing. Can I get instructions for including drivers into a Yocto Build please? I have both EM9191 and EM9291 devices on boards. What dependencies are needed and anything else. Detailed steps would be appreciated. Was having issues manually trying to include them from terminal. Thank you in advance

Our MBPL USB driver actually just modifies the qcserial.c

You can use the toolchain of your platform and cross-compile the qcserial driver.
After that you can use inmod command to add the driver to your yocto platform

Furthermore, you also need to include MBIM driver for your yocto build
