Subject: [PATCH v5 2/3] dt-bindings: net: support for Allwinner R40 EMAC controller
Date: Thu, 13 Jan 2022 08:37:33 +0300 [thread overview]
Message-ID: <20220113053734.105813-3-boger@wirenboard.com> (raw)
In-Reply-To: <20220113053734.105813-1-boger@wirenboard.com>
R40 and A10/A20 share the same EMAC IP.
However, on R40 the EMAC reset needs to be deasserted first,
so resets property is required.
Signed-off-by: Evgeny Boger <boger@wirenboard.com>
