Subject: [PATCH 4/7] state: support deep probe
Date: Mon, 28 Jun 2021 08:45:14 +0200	[thread overview]
Message-ID: <20210628064517.28636-5-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20210628064517.28636-1-a.fatoum@pengutronix.de>

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.
