From b6ff27217e58d3b3a900debbd90924375aa62d30 Mon Sep 17 00:00:00 2001 From: Martin Blumenstingl Date: Sun, 19 Feb 2017 22:41:41 +0100 Subject: [PATCH] ARM64: dts: meson-gxbb-odroidc2: add the ethernet PHY's reset GPIO This resets the ethernet PHY during boot to get the PHY into a "clean" state. While here also explicitly specify the phy-mode instead of relying on the default-value from meson-gx.dtsi.
