++MediaTek Frame Engine Ethernet controller
++=========================================
++
++The frame engine ethernet controller can be found on MediaTek SoCs. These SoCs
++have dual GMAC each represented by a child node..
++
++* Ethernet controller node
++
++Required properties:
++- compatible: Should be "mediatek,mt7623-eth"
++- reg: Address and length of the register set for the device
++- interrupts: Should contain the frame engines interrupt
++- clocks: the clock used by the core
++- clock-names: the names of the clock listed in the clocks property. These are
++ "ethif", "esw", "gp2", "gp1"
++- power-domains: phandle to the power domain that the ethernet is part of
++- resets: Should contain a phandle to the ethsys reset signal
++- reset-names: Should contain the reset signal name "eth"
++- mediatek,ethsys: phandle to the syscon node that handles the port setup
++- mediatek,pctl: phandle to the syscon node that handles the ports slew rate
++ and driver current
++
++Optional properties:
++- interrupt-parent: Should be the phandle for the interrupt controller
++ that services interrupts for this device
++
++
++* Ethernet MAC node
++
++Required properties:
++- compatible: Should be "mediatek,eth-mac"
++- reg: The number of the MAC
++- phy-handle: see ethernet.txt file in the same directory.
++
++Example:
++
++eth: ethernet@1b100000 {
++ compatible = "mediatek,mt7623-eth";
++ reg = <0 0x1b100000 0 0x20000>;
++ clocks = <&topckgen CLK_TOP_ETHIF_SEL>,
++ <&ethsys CLK_ETHSYS_ESW>,
++ <&ethsys CLK_ETHSYS_GP2>,
++ <&ethsys CLK_ETHSYS_GP1>;
++ clock-names = "ethif", "esw", "gp2", "gp1";
++ interrupts = <GIC_SPI 200 IRQ_TYPE_LEVEL_LOW>;
++ power-domains = <&scpsys MT2701_POWER_DOMAIN_ETH>;
++ resets = <&ethsys MT2701_ETHSYS_ETH_RST>;
++ reset-names = "eth";
++ mediatek,ethsys = <&ethsys>;
++ mediatek,pctl = <&syscfg_pctl_a>;
++ #address-cells = <1>;
++ #size-cells = <0>;
++
++ gmac1: mac@0 {
++ compatible = "mediatek,eth-mac";
++ reg = <0>;
++ phy-handle = <&phy0>;
++ };
++
++ gmac2: mac@1 {
++ compatible = "mediatek,eth-mac";
++ reg = <1>;
++ phy-handle = <&phy1>;
++ };
++
++ mdio-bus {
++ phy0: ethernet-phy@0 {
++ reg = <0>;
++ phy-mode = "rgmii";
++ };
++
++ phy1: ethernet-phy@1 {
++ reg = <1>;
++ phy-mode = "rgmii";
++ };
++ };
++};
