Merge tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC fixes from Olof Johansson: "A couple of late-arriving fixes before final 4.13: - A few reverts of DT bindings on Allwinner for their ethernet driver. Discussion didn't converge, and since bindings are considered ABI it makes sense to revert instead of having to support two bindings long-term. - A fix to enumerate GPIOs properly on Marvell Armada AP806" * tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: arm64: dts: marvell: fix number of GPIOs in Armada AP806 description arm: dts: sunxi: Revert EMAC changes arm64: dts: allwinner: Revert EMAC changes dt-bindings: net: Revert sun8i dwmac binding

-* Allwinner sun8i GMAC ethernet controller
-
-This device is a platform glue layer for stmmac.
-Please see stmmac.txt for the other unchanged properties.
-
-Required properties:
-- compatible: should be one of the following string:
- "allwinner,sun8i-a83t-emac"
- "allwinner,sun8i-h3-emac"
- "allwinner,sun8i-v3s-emac"
- "allwinner,sun50i-a64-emac"
-- reg: address and length of the register for the device.
-- interrupts: interrupt for the device
-- interrupt-names: should be "macirq"
-- clocks: A phandle to the reference clock for this device
-- clock-names: should be "stmmaceth"
-- resets: A phandle to the reset control for this device
-- reset-names: should be "stmmaceth"
-- phy-mode: See ethernet.txt
-- phy-handle: See ethernet.txt
-- #address-cells: shall be 1
-- #size-cells: shall be 0
-- syscon: A phandle to the syscon of the SoC with one of the following
- compatible string:
- - allwinner,sun8i-h3-system-controller
- - allwinner,sun8i-v3s-system-controller
- - allwinner,sun50i-a64-system-controller
- - allwinner,sun8i-a83t-system-controller
-
-Optional properties:
-- allwinner,tx-delay-ps: TX clock delay chain value in ps. Range value is 0-700. Default is 0)
-- allwinner,rx-delay-ps: RX clock delay chain value in ps. Range value is 0-3100. Default is 0)
-Both delay properties need to be a multiple of 100. They control the delay for
-external PHY.
-
-Optional properties for the following compatibles:
- - "allwinner,sun8i-h3-emac",
- - "allwinner,sun8i-v3s-emac":
-- allwinner,leds-active-low: EPHY LEDs are active low
-
-Required child node of emac:
-- mdio bus node: should be named mdio
-
-Required properties of the mdio node:
-- #address-cells: shall be 1
-- #size-cells: shall be 0
-
-The device node referenced by "phy" or "phy-handle" should be a child node
-of the mdio node. See phy.txt for the generic PHY bindings.
-
-Required properties of the phy node with the following compatibles:
- - "allwinner,sun8i-h3-emac",
- - "allwinner,sun8i-v3s-emac":
-- clocks: a phandle to the reference clock for the EPHY
-- resets: a phandle to the reset control for the EPHY
-
-Example:
-
-emac: ethernet@1c0b000 {
- compatible = "allwinner,sun8i-h3-emac";
- syscon = <&syscon>;
- reg = <0x01c0b000 0x104>;

- reset-names = "stmmaceth";
- clocks = <&ccu CLK_BUS_EMAC>;
- clock-names = "stmmaceth";
- #address-cells = <1>;
- #size-cells = <0>;
-
- phy-handle = <&int_mii_phy>;
- phy-mode = "mii";
- allwinner,leds-active-low;
- mdio: mdio {
- #address-cells = <1>;
- #size-cells = <0>;
