The <M> means that it can be inserted as a module but is not loaded on default.
If you go that option and press <space bar> it will toggle between *, y, n Or M
Y means that it is included as default ie statically linked. You might need to do that.
Now if you want to know which drivers this driver depends on,
modproble <driver_name> in the shell.
It will try to load the module and show you which ones are loaded before it in exactly that order
However you might need to find the .ko file where your module is located.
the .ko files are there in /lib/kernel/linux-yocto-* / I think
Navigate to them and do modprobe.
