The vPE handles packet processing, routing, QinQ encapsulation, flows, ACL rules, adds/removes MPLS tags and performs QoS
\nThe KPI is the number of packets per second for a specified packet size (min packet size is 68 byte) with an accepted minimal packet loss
\n* Renesas Multi-Function Timer Pulse Unit 2 (MTU2)
The MTU2 is a multi-purpose, multi-channel timer/counter with configurable
clock inputs and programmable compare match.
Channels share hardware resources but their counter and compare match value
are independent. The MTU2 hardware supports five channels indexed from 0 to 4.
Required Properties:
- compatible: must be one or more of the following:
- "renesas,mtu2-r7s72100" for the r7s72100 MTU2
- "renesas,mtu2" for any MTU2
This is a fallback for the above renesas,mtu2-* entries
- reg: base address and length of the registers block for the timer module.
- interrupts: interrupt specifiers for the timer, one for each entry in
interrupt-names.
- interrupt-names: must contain one entry named "tgi?a" for each enabled
channel, where "?" is the channel index expressed as one digit from "0" to
"4".
- clocks: a list of phandle + clock-specifier pairs, one for each entry
in clock-names.
- clock-names: must contain "fck" for the functional clock.
Example: R7S72100 (RZ/A1H) MTU2 node
