From 9813395078352fed03c88742bd39b9c4a0e40c15 Mon Sep 17 00:00:00 2001 From: Michael Opdenacker Date: Wed, 22 Oct 2025 20:18:38 +0000 Subject: [PATCH] riscv: dts: spacemit: add Ethernet and PDMA to OrangePi RV2 The OrangePi RV2 board ships two RGMII ethernet ports. Each has an external Motorcomm YT8531C PHY attached, the PHY uses GPIO for reset pin control. Enable PDMA for the SpacemiT K1-based SoC in the OrangePi RV2 board.
