No, NEVER do that.  platform devices are only for real platform devices,
do not abuse that interface any more than it already is.

No, not at all, sorry.

Use a real device, you have one somewhere that relates to this hardware,
otherwise you aren't controlling anything and then you can use a virtual
device.

Again, do NOT abuse the platform subsystem.  It's one reason I am loath
to even want to allow rust bindings to it.
