From be5f7befbd75ec95f0d444813ae85e26851eff3b Mon Sep 17 00:00:00 2001 From: Martin Blumenstingl Date: Sun, 19 Feb 2017 22:41:45 +0100 Subject: ARM64: dts: meson-gxbb-wetek-hub: 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 specify the phy-handle of the ethmac node to make the PHY configuration similar to the one we have on GXL devices. This will allow us to specify OF-properties for the PHY itself.
