Subject: [PATCH net-next v3 3/5] riscv: dts: spacemit: Add Ethernet support for K1
Date: Wed, 02 Jul 2025 14:01:42 +0800 [thread overview]
Message-ID: <20250702-net-k1-emac-v3-3-882dc55404f3@iscas.ac.cn> (raw)
In-Reply-To: <20250702-net-k1-emac-v3-0-882dc55404f3@iscas.ac.cn>
Add nodes for each of the two Ethernet MACs on K1 with generic
properties. Also add "gmac" pins to pinctrl config.
Signed-off-by: Vivian Wang <wangruikang@iscas.ac.cn>
