From a246e21351778a93805b3f52302a420f4b268601 Mon Sep 17 00:00:00 2001 From: Stefan Agner Date: Thu, 8 Apr 2021 10:25:28 +0200 Subject: [PATCH] arm64: dts: meson: odroidc2: readd PHY reset properties The sync of the device tree and dt-bindings from Linux v5.6-rc2 11a48a5a18c6 ("Linux 5.6-rc2") causes Ethernet to break on some ODROID-C2. The PHY seems to need proper reset timing to be functional in U-Boot and Linux afterwards. Readd the old PHY reset bindings for dwmac until we support the new bindings in the PHY node.
