Subject: [PATCH v5 1/2] dt-bindings: rng: bcm2835: document reset support
Date: Thu,  4 Mar 2021 08:33:07 +0100	[thread overview]
Message-ID: <20210304073308.25906-2-noltari@gmail.com> (raw)
In-Reply-To: <20210304073308.25906-1-noltari@gmail.com>

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

Signed-off-by: Álvaro Fernández Rojas <noltari@gmail.com>

 v5: no changes.
 v4: pass dt_binding_check.
 v3: make resets required if brcm,bcm6368-rng.
 v2: document reset support.
