| 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 |
| tstamper: timestamper@60000000 { |
| compatible = "ines,ptp-ctrl"; |
| timestamper = <&tstamper 0>; |
