dt-bindings: net: qcom,ethqos: Convert bindings to yaml 



Convert Qualcomm ETHQOS Ethernet devicetree binding to YAML.
In doing so add a new property for iommus since newer platforms support
using one, and without such make dtbs_check fails on them.

While at it, also update the MAINTAINERS file to point to the yaml
version of the bindings.

Qualcomm Ethernet ETHQOS device



This documents dwmmac based ethernet device which supports Gigabit

ethernet for version v2.3.0 onwards.



This device has following properties:



Required properties:



- compatible: Should be one of:

		"qcom,qcs404-ethqos"

		"qcom,sm8150-ethqos"



- reg: Address and length of the register set for the device



- reg-names: Should contain register names "stmmaceth", "rgmii"



- clocks: Should contain phandle to clocks



- clock-names: Should contain clock names "stmmaceth", "pclk",

		"ptp_ref", "rgmii"



- interrupts: Should contain phandle to interrupts



- interrupt-names: Should contain interrupt names "macirq", "eth_lpi"



Rest of the properties are defined in stmmac.txt file in same directory





Example:



ethernet: ethernet@7a80000 {

	compatible = "qcom,qcs404-ethqos";

	reg = <0x07a80000 0x10000>,

		<0x07a96000 0x100>;

	reg-names = "stmmaceth", "rgmii";

	clock-names = "stmmaceth", "pclk", "ptp_ref", "rgmii";

	clocks = <&gcc GCC_ETH_AXI_CLK>,

		<&gcc GCC_ETH_SLAVE_AHB_CLK>,

		<&gcc GCC_ETH_PTP_CLK>,

		<&gcc GCC_ETH_RGMII_CLK>;

	interrupts = <GIC_SPI 56 IRQ_TYPE_LEVEL_HIGH>,

			<GIC_SPI 55 IRQ_TYPE_LEVEL_HIGH>;

	interrupt-names = "macirq", "eth_lpi";

	snps,reset-gpio = <&tlmm 60 GPIO_ACTIVE_LOW>;

	snps,reset-active-low;



	snps,txpbl = <8>;

	snps,rxpbl = <2>;

	snps,aal;

	snps,tso;



	phy-handle = <&phy1>;

	phy-mode = "rgmii";



	mdio {

		#address-cells = <0x1>;

		#size-cells = <0x0>;

		compatible = "snps,dwmac-mdio";

		phy1: phy@4 {

			device_type = "ethernet-phy";

			reg = <0x4>;

		};

	};
