* 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. |
|
|
|
- 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. |
