Yep

That's essentially what I did with the gpio and gpio-event stuff
(kernel modules, user libs and user apps). You can call make directly
to build them, or you can use bitbake. I found using bitbake during
actual development was too slow.

So the makefiles for gpio and gpio-event stuff can also be used as an example.
