  1. Imagination Pistachio SoC
  2. =========================
  3. Required properties:
  4. --------------------
  5. - compatible: Must include "img,pistachio".
  6. CPU nodes:
  7. ----------
  8. A "cpus" node is required. Required properties:
  9. - #address-cells: Must be 1.
  10. - #size-cells: Must be 0.
  11. A CPU sub-node is also required for at least CPU 0. Since the topology may
  12. be probed via CPS, it is not necessary to specify secondary CPUs. Required
  13. propertis:
  14. - device_type: Must be "cpu".
  15. - compatible: Must be "mti,interaptiv".
  16. - reg: CPU number.
  17. - clocks: Must include the CPU clock. See ../../clock/clock-bindings.txt for
  18. details on clock bindings.
  19. Example:
  20. cpus {
  21. #address-cells = <1>;
  22. #size-cells = <0>;
  23. cpu0: cpu@0 {
  24. device_type = "cpu";
  25. compatible = "mti,interaptiv";
  26. reg = <0>;
  27. clocks = <&clk_core CLK_MIPS>;
  28. };
  29. };
  30. Boot protocol:
  31. --------------
  32. In accordance with the MIPS UHI specification[1], the bootloader must pass the
  33. following arguments to the kernel:
  34. - $a0: -2.
  35. - $a1: KSEG0 address of the flattened device-tree blob.
