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 qcom,qcs404-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
