+This node models the Qualcomm Technologies Low-Power Audio SubSystem (LPASS).
+Required properties:
+- compatible : "qcom,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"+- 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.txtfor 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"+Required subnodes:
+- qcom,adsp : Audio DSP sub-node
What is the intent of this subnode?
+Optional Audio DSP subnode properties:
+- status : "disabled" indicates the adsp is not available.
+Example:
+lpass@28100000 {
- compatible = "qcom,lpass-cpu";
- clocks = <&lcc AHBIX_CLK>, <&lcc MI2S_OSR_CLK>, <&lcc MI2S_BIT_CLK>;
- clock-names = "ahbix-clk", "mi2s-osr-clk", "mi2s-bit-clk";
- 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 {
