From f89b58ce71a949ca3592728b586d2077b6cc7ecc Mon Sep 17 00:00:00 2001 From: Mikko Perttunen Date: Wed, 20 Jun 2018 15:54:06 +0300 Subject: [PATCH] arm64: tegra: Add ethernet controller on Tegra194 The Tegra194 contains the same ethernet controller as the Tegra186. Add the device tree node for it, and correspondingly the PHY node on the board device tree.
