1 This document describes the device tree bindings associated with the
6 switch sub-module to send and receive packets. NetCP also includes a packet
13 includes a 3-port Ethernet switch sub-module capable of 10Gb/s and 1Gb/s rates
16 Keystone NetCP driver has a plug-in module architecture where each of the NetCP
17 sub-modules exist as a loadable kernel module which plug in to the netcp core.
18 These sub-modules are represented as "netcp-devices" in the dts bindings. It is
19 mandatory to have the ethernet switch sub-module for the ethernet interface to
20 be operational. Any other sub-module like the PA is optional.
