Subject: [PATCH 2/2] dt-bindings: net: mdio: update reset-delay-us description
Date: Tue, 28 Jul 2020 11:02:03 +0200 [thread overview]
Message-ID: <20200728090203.17313-2-bruno.thomsen@gmail.com> (raw)
In-Reply-To: <20200728090203.17313-1-bruno.thomsen@gmail.com>
Property is now used for both assert and deassert delay
so PHYs can be reset before type id auto detection.
