  1. Broadcom BCM53573 ILP clock
  2. ===========================
  3. This binding uses the common clock binding:
  4. Documentation/devicetree/bindings/clock/clock-bindings.txt
  5. This binding is used for ILP clock (sometimes referred as "slow clock")
  6. on Broadcom BCM53573 devices using Cortex-A7 CPU.
  7. ILP's rate has to be calculated on runtime and it depends on ALP clock
  8. which has to be referenced.
  9. This clock is part of PMU (Power Management Unit), a Broadcom's device
  10. handing power-related aspects. Its node must be sub-node of the PMU
  11. device.
  12. Required properties:
  13. - compatible: "brcm,bcm53573-ilp"
  14. - clocks: has to reference an ALP clock
  15. - #clock-cells: should be <0>
  16. - clock-output-names: from common clock bindings, should contain clock
  17. name
  18. Example:
  19. pmu@18012000 {
  20. compatible = "simple-mfd", "syscon";
  21. reg = <0x18012000 0x00001000>;
  22. ilp {
  23. compatible = "brcm,bcm53573-ilp";
  24. clocks = <&alp>;
  25. #clock-cells = <0>;
  26. clock-output-names = "ilp";
  27. };
  28. };
