Subject: [PATCH v6 2/4] riscv: dts: starfive: jh7100-common: Setup pinmux and enable gmac
Date: Wed, 20 Dec 2023 23:17:40 +0200	[thread overview]
Message-ID: <20231220211743.2490518-3-cristian.ciocaltea@collabora.com> (raw)
In-Reply-To: <20231220211743.2490518-1-cristian.ciocaltea@collabora.com>

Add pinmux configuration for DWMAC found on the JH7100 based boards and
enable the related DT node, providing a basic PHY configuration.
