+Subject: [PATCH] net: stmmac: snps, dwmac-mdio MDIOs are automatically
+ registered
+
+stmmac bindings docs said that its mdio node must have
+compatible = "snps,dwmac-mdio";
+Since dwmac-sun8i does not have any good reasons to not doing it, all
+their MDIO node must have it.
+
+Since these compatible is automatically registered, dwmac-sun8i compatible
+does not need to be in need_mdio_ids.

+Subject: [PATCH] net: stmmac: dwmac-sun8i: Handle integrated/external MDIOs
+
+The Allwinner H3 SoC have two distinct MDIO bus, only one could be
+active at the same time.
+The selection of the active MDIO bus are done via some bits in the EMAC
+register of the system controller.
+
+This patch implement this MDIO switch via a custom MDIO-mux.

+
+The driver expect "allwinner,leds-active-low" to be in PHY node, but
+the binding doc expect it to be in MAC node.
+
+Since all board DT use it also in MAC node, the driver need to search
+allwinner,leds-active-low in MAC node.

+Subject: [PATCH] ARM: dts: sunxi: Restore EMAC changes (boards)
+
+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 all boards DT about dwmac-sun8i
+This reverts partially commit fe45174b72ae ("arm: dts: sunxi: Revert EMAC changes")

+Subject: [PATCH] arm64: dts: allwinner: 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 arm64 DT about dwmac-sun8i for H5
+This reverts a part of commit 87e1f5e8bb4b ("arm64: dts: allwinner: Revert EMAC changes")
