ZHAW InES PTP time stamping IP core
|
|
|
|
The IP core needs two different kinds of nodes. The control node
|
|
lives somewhere in the memory map and specifies the address of the
|
|
control registers. There can be up to three port handles placed as
|
|
attributes of PHY nodes. These associate a particular MII bus with a
|
|
port index within the IP core.
|
|
|
|
Required properties of the control node:
|
|
|
|
- compatible: "ines,ptp-ctrl"
|
|
- reg: physical address and size of the register bank
|
|
|
|
Required format of the port handle within the PHY node:
|
|
|
|
- timestamper: provides control node reference and
|
|
the port channel within the IP core
|
|
|
|
Example:
|
|
|
|
tstamper: timestamper@60000000 {
|
|
compatible = "ines,ptp-ctrl";
|
|
reg = <0x60000000 0x80>;
|
|
};
|
|
|
|
ethernet@80000000 {
|
|
...
|
|
mdio {
|
|
...
|
|
ethernet-phy@3 {
|
|
...
|
|
timestamper = <&tstamper 0>;
|
|
};
|
|
};
|
|
};
