The PIP Ethernet nexus can control several data packet input/output devices. The devices have a two level grouping scheme. There may be several interfaces, and each interface may have several ports. These ports might be an individual Ethernet PHY. Properties for the PIP nexus: - compatible: "cavium,octeon-3860-pip" Compatibility with all cn3XXX, cn5XXX and cn6XXX SOCs. - reg: The base address of the PIP's register bank. - #address-cells: Must be <1>. - #size-cells: Must be <0>. Properties for PIP interfaces which is a child the PIP nexus: - compatible: "cavium,octeon-3860-pip-interface" Compatibility with all cn3XXX, cn5XXX and cn6XXX SOCs. - reg: The interface number. - #address-cells: Must be <1>. - #size-cells: Must be <0>. Properties for PIP port which is a child the PIP interface: - compatible: "cavium,octeon-3860-pip-port" Compatibility with all cn3XXX, cn5XXX and cn6XXX SOCs. - reg: The port number within the interface group. - phy-handle: Optional, see ethernet.txt file in the same directory. - rx-delay: Delay value for RGMII receive clock. Optional. Disabled if 0. Value range is 1-31, and mapping to the actual delay varies depending on HW. - tx-delay: Delay value for RGMII transmit clock. Optional. Disabled if 0. Value range is 1-31, and mapping to the actual delay varies depending on HW.
