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	
38	- phy-handle: Optional, see ethernet.txt file in the same directory.
