Are those buttons configurable in some way? Or do they have a fixed purpose?
How does Android handle those buttons, BTW?

I would say that it should be described in device tree if the purpose is
fixed. For example, if there is no display behind the touch screen at a
certain point but a printed sheet (e.g., with a home or return symbol)
then it is clear that this button is not going to change. In such a case
I doubt that flexibility is required.
Best regards, Michael
