Subject: [PATCH net-next v2 1/2] dt-bindings: net: allwinner: add H616 EMAC1
Date: Tue, 15 Sep 2026 21:07:40 -0600 [thread overview]
Message-ID: <20260915-submit-h616-emac1-v1-v2-1-322b32e40eb9@gmail.com> (raw)
In-Reply-To: <20260915-submit-h616-emac1-v1-v2-0-322b32e40eb9@gmail.com>
The H616 secondary EMAC uses a separate system-control clock register
and supports only RMII at 10/100 Mbps. Add its distinct compatible
without an older fallback, since using the primary EMAC clock register
would not work.
Constrain the PHY interface mode to RMII, matching the hardware.
