From a3606e8a7819534026b46e2b8c7b0e156e292f13 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Tue, 23 Sep 2025 22:02:46 +0800 Subject: [PATCH] arm64: dts: allwinner: t527: orangepi-4a: Enable Ethernet port On the Orangepi 4A board, the second Ethernet controller, aka the GMAC200, is connected to an external Motorcomm YT8531 PHY. The PHY uses an external 25MHz crystal, has the SoC's PI15 pin connected to its reset pin, and the PI16 pin for its interrupt pin. Enable it.
