  1. Coherency fabric
  2. ----------------
  3. Available on Marvell SOCs: Armada 370, Armada 375, Armada 38x and Armada XP
  4. Required properties:
  5. - compatible: the possible values are:
  6. * "marvell,coherency-fabric", to be used for the coherency fabric of
  7. the Armada 370 and Armada XP.
  8. * "marvell,armada-375-coherency-fabric", for the Armada 375 coherency
  9. fabric.
  10. * "marvell,armada-380-coherency-fabric", for the Armada 38x coherency
  11. fabric.
  12. - reg: Should contain coherency fabric registers location and
  13. length.
  14. * For "marvell,coherency-fabric", the first pair for the coherency
  15. fabric registers, second pair for the per-CPU fabric registers.
  16. * For "marvell,armada-375-coherency-fabric", only one pair is needed
  17. for the per-CPU fabric registers.
  18. * For "marvell,armada-380-coherency-fabric", only one pair is needed
  19. for the per-CPU fabric registers.
  20. Optional properties:
  21. - broken-idle: boolean to set when the Idle mode is not supported by the
  22. hardware.
  23. Examples:
  24. coherency-fabric@d0020200 {
  25. compatible = "marvell,coherency-fabric";
  26. reg = <0xd0020200 0xb0>,
  27. <0xd0021810 0x1c>;
  28. };
  29. coherency-fabric@21810 {
  30. compatible = "marvell,armada-375-coherency-fabric";
  31. reg = <0x21810 0x1c>;
  32. };
