Subject: [PATCH v2 2/2] riscv: dts: sophgo: add Milk-V Duo ethernet DTB
Date: Wed, 04 Nov 2026 11:52:34 -0300 [thread overview]
Message-ID: <20261104-milkv-duo-eth-overlay-v2-2-e3d2d39cf229@baylibre.com> (raw)
In-Reply-To: <20261104-milkv-duo-eth-overlay-v2-0-e3d2d39cf229@baylibre.com>
Add a DTB that applies the shared cv18xx-eth.dtbo overlay to the Milk-V
Duo (CV1800B) base DTB. This enables gmac0 and the internal PHY MDIO mux
on boards with the Ethernet IO board, matching the existing Milk-V Duo
256M DTB.
