Kernel-4.18.0-80.el8_qcom,lpass-cpu

• Qualcomm Technologies LPASS CPU DAI

This node models the Qualcomm Technologies Low-Power Audio SubSystem (LPASS).

Required properties:

• compatible : “qcom,lpass-cpu” or “qcom,apq8016-lpass-cpu”

• clocks : Must contain an entry for each entry in clock-names.

• clock-names : A list which must include the following entries:

            * "ahbix-clk"
            * "mi2s-osr-clk"
            * "mi2s-bit-clk"
        : required clocks for "qcom,lpass-cpu-apq8016"
            * "ahbix-clk"
            * "mi2s-bit-clk0"
            * "mi2s-bit-clk1"
            * "mi2s-bit-clk2"
            * "mi2s-bit-clk3"
            * "pcnoc-mport-clk"
            * "pcnoc-sway-clk"
  

• interrupts : Must contain an entry for each entry in

          interrupt-names.
  

• interrupt-names : A list which must include the following entries:

            * "lpass-irq-lpaif"
  

• pinctrl-N : One property must exist for each entry in

          pinctrl-names.  See ../pinctrl/pinctrl-bindings.txt
          for details of the property values.
  

• pinctrl-names : Must contain a “default” entry.

• reg : Must contain an address for each entry in reg-names.

• reg-names : A list which must include the following entries:

            * "lpass-lpaif"
  

Optional properties:

• qcom,adsp : Phandle for the audio DSP node

interrupts = <0 85 1>;
interrupt-names = “lpass-irq-lpaif”;
pinctrl-names = “default”, “idle”;
pinctrl-0 = <&mi2s_default>;
pinctrl-1 = <&mi2s_idle>;
reg = <0x28100000 0x10000>;
reg-names = “lpass-lpaif”;
qcom,adsp = <&adsp>;
