* PIP Ethernet nexus.
|
|
|
|
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.
|
|
|
|
- mac-address: Optional, the MAC address to assign to the device.
|
|
|
|
- local-mac-address: Optional, the MAC address to assign to the device
|
|
if mac-address is not specified.
|
|
|
|
- phy-handle: Optional, a phandle for the PHY device connected to this device.
