It provides a +number of shared PHYs used by various interfaces (network, sata, usb, +PCIe...). + +Required properties: + +- compatible: should be "marvell,armada-380-comphy" +- reg: should contain the comphy register location and length. +- #address-cells: should be 1. +- #size-cells: should be 0. + +Optional properties: + +- reg-names: must be "comphy" as the first name, and "conf". +- reg: must contain the comphy register location and length as the first + pair, followed by an optional configuration register address and + length pair. + +A sub-node is required for each comphy lane provided by the comphy. + +Required properties (child nodes): + +- reg: comphy lane number. +- #phy-cells : from the generic phy bindings, must be 1.
