Subject: [PATCH v2 1/3] dt-bindings: net: sophgo,sg2044-dwmac: add phy mode restriction
Date: Mon, 20 Oct 2025 17:54:57 +0800 [thread overview]
Message-ID: <20251020095500.1330057-2-inochiama@gmail.com> (raw)
In-Reply-To: <20251020095500.1330057-1-inochiama@gmail.com>
As the ethernet controller of SG2044 and SG2042 only supports
RGMII phy. Add phy-mode property to restrict the value.
Also, since SG2042 has internal rx delay in its mac, make
only "rgmii-txid" and "rgmii-id" valid for phy-mode.
