If I understand it correctly, this is a property of how the
driver works, not how the hardware works / is connected; so
there should be _no_ such property in the device tree.

If I understand that wrong :-), just keep mode = "cpu", but
add an extra (empty) property representing that you need some
quirky mode special thing.

Either way, don't use underscores.
