As I understood it so far, the purpose of the devicetree is done as soon
it is presented to the linux-kernel and once parsed during boot.
Changing it at runtime and reacting to that looks like a bigger step to
me. Hints for that are that most fdt-functions are __init and I couldn't
quickly find an add_node-function...
Shouldn't really matter anyhow, should it? As soon as we are run-time,
there shouldn't be any difference between DTS and platform_devices. It
is just driver-model then...
