Subject: [PATCH 1/8] 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.

But now we have a solution so we need to get back that was reverted.

Subject: [PATCH 4/8] arm64: dts: allwinner: add snps,dwmac-mdio compatible to
emac/mdio
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.

Subject: [PATCH 5/8] 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")

Subject: [PATCH 7/8] 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")

Subject: [PATCH 8/8] ARM: dts: sunxi: h3/h5: represent the mdio switch used by
sun8i-h3-emac
Since dwmac-sun8i could use either an integrated PHY or an external PHY
(which could be at same MDIO address), we need to represent this selection
by a MDIO switch.
