1 | * PIP Ethernet nexus. |
| 2 | ||
| 3 | The PIP Ethernet nexus can control several data packet input/output | |
| 4 | devices. The devices have a two level grouping scheme. There may be | |
| 5 | several interfaces, and each interface may have several ports. These | |
| 6 | ports might be an individual Ethernet PHY. | |
| 7 | ||
| 8 | ||
| 9 | Properties for the PIP nexus: | |
| 10 | - compatible: "cavium,octeon-3860-pip" | |
| 11 | ||
| 12 | Compatibility with all cn3XXX, cn5XXX and cn6XXX SOCs. | |
| 13 | ||
| 14 | - reg: The base address of the PIP's register bank. | |
| 15 | ||
| 16 | - #address-cells: Must be <1>. | |
| 17 | ||
| 18 | - #size-cells: Must be <0>. | |
| 19 | ||
| 20 | Properties for PIP interfaces which is a child the PIP nexus: | |
| 21 | - compatible: "cavium,octeon-3860-pip-interface" | |
| 22 | ||
| 23 | Compatibility with all cn3XXX, cn5XXX and cn6XXX SOCs. | |
| 24 | ||
| 25 | - reg: The interface number. | |
| 26 | ||
| 27 | - #address-cells: Must be <1>. | |
| 28 | ||
| 29 | - #size-cells: Must be <0>. | |
| 30 | ||
| 31 | Properties for PIP port which is a child the PIP interface: | |
| 32 | - compatible: "cavium,octeon-3860-pip-port" | |
| 33 | ||
| 34 | Compatibility with all cn3XXX, cn5XXX and cn6XXX SOCs. | |
| 35 | ||
| 36 | - reg: The port number within the interface group. | |
| 37 | ||
| e8f08ee0 | 38 | - phy-handle: Optional, see ethernet.txt file in the same directory. |
