Subject: [PATCH v3 1/2] dt-bindings: rng: bcm2835: document reset support
Date: Tue, 23 Feb 2021 18:00:05 +0100	[thread overview]
Message-ID: <20210223170006.29558-2-noltari@gmail.com> (raw)
In-Reply-To: <20210223170006.29558-1-noltari@gmail.com>

Some devices may need to perform a reset before using the RNG, such as the
BCM6368.
