  1. * Qualcomm Technologies LPASS CPU DAI
  2. This node models the Qualcomm Technologies Low-Power Audio SubSystem (LPASS).
  3. Required properties:
  4. - compatible : "qcom,lpass-cpu" or "qcom,apq8016-lpass-cpu"
  5. - clocks : Must contain an entry for each entry in clock-names.
  6. - clock-names : A list which must include the following entries:
  7. * "ahbix-clk"
  8. * "mi2s-osr-clk"
  9. * "mi2s-bit-clk"
  10. : required clocks for "qcom,lpass-cpu-apq8016"
  11. * "ahbix-clk"
  12. * "mi2s-bit-clk0"
  13. * "mi2s-bit-clk1"
  14. * "mi2s-bit-clk2"
  15. * "mi2s-bit-clk3"
  16. * "pcnoc-mport-clk"
  17. * "pcnoc-sway-clk"
  18. - interrupts : Must contain an entry for each entry in
  19. interrupt-names.
  20. - interrupt-names : A list which must include the following entries:
  21. * "lpass-irq-lpaif"
  22. - pinctrl-N : One property must exist for each entry in
  23. pinctrl-names. See ../pinctrl/pinctrl-bindings.txt
  24. for details of the property values.
  25. - pinctrl-names : Must contain a "default" entry.
  26. - reg : Must contain an address for each entry in reg-names.
  27. - reg-names : A list which must include the following entries:
  28. * "lpass-lpaif"
  29. Optional properties:
  30. - qcom,adsp : Phandle for the audio DSP node
  31. Example:
  32. lpass@28100000 {
  33. compatible = "qcom,lpass-cpu";
  34. clocks = <&lcc AHBIX_CLK>, <&lcc MI2S_OSR_CLK>, <&lcc MI2S_BIT_CLK>;
  35. clock-names = "ahbix-clk", "mi2s-osr-clk", "mi2s-bit-clk";
  36. interrupts = <0 85 1>;
  37. interrupt-names = "lpass-irq-lpaif";
  38. pinctrl-names = "default", "idle";
  39. pinctrl-0 = <&mi2s_default>;
  40. pinctrl-1 = <&mi2s_idle>;
  41. reg = <0x28100000 0x10000>;
  42. reg-names = "lpass-lpaif";
  43. qcom,adsp = <&adsp>;
  44. };
