|    state: support deep probe
|
|    With deep probe, drivers registered before of_populate_initcall must
|    themselves take care to ensure their dependencies had a chance to probe.
|
|    For barebox-state, this means the backend partition provider must be
|    probed. Do so by calling of_partition_ensure_probed on it.
