  1. Fixed link Device Tree binding
  2. ------------------------------
  3. Some Ethernet MACs have a "fixed link", and are not connected to a
  4. normal MDIO-managed PHY device. For those situations, a Device Tree
  5. binding allows to describe a "fixed link".
  6. Such a fixed link situation is described by creating a 'fixed-link'
  7. sub-node of the Ethernet MAC device node, with the following
  8. properties:
  9. * 'speed' (integer, mandatory), to indicate the link speed. Accepted
  10. values are 10, 100 and 1000
  11. * 'full-duplex' (boolean, optional), to indicate that full duplex is
  12. used. When absent, half duplex is assumed.
  13. * 'pause' (boolean, optional), to indicate that pause should be
  14. enabled.
  15. * 'asym-pause' (boolean, optional), to indicate that asym_pause should
  16. be enabled.
  17. Examples:
  18. ethernet@0 {
  19. ...
  20. fixed-link {
  21. speed = <1000>;
  22. full-duplex;
  23. };
  24. ...
  25. };
