+Subject: [PATCH] arm: dts: sunxi: h3/h5: Restore EMAC changes
+
+The original dwmac-sun8i DT bindings have some issue on how to handle
+integrated PHY and was reverted in last RC of 4.13.
+But now we have a solution so we need to get back that was reverted.
+
+This patch restore sunxi-h3-h5.dtsi
+This reverts partially commit fe45174b72ae ("arm: dts: sunxi: Revert EMAC changes")
