From 7ea519de7186d30d2147dcc11bc249c0a3ce86ff Mon Sep 17 00:00:00 2001 From: Jerry Ray Date: Fri, 9 Sep 2022 11:30:22 -0500 Subject: [PATCH] dts: arm: at91: Add SAMA5D3-EDS Board The SAMA5D3-EDS board is an Ethernet Development Platform allowing for evaluating many Microchip ethernet switch and PHY products. Various daughter cards can connect via an RGMII connector or an RMII connector. The EDS board is not intended for stand-alone use and has no ethernet capabilities when no daughter board is connected. As such, this device tree is intended to be used with a DT overlay defining the add-on board. To better ensure consistency, some items are defined here as a form of documentation so that all add-on overlays will use the same terms.
