- 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
Example:
lpass@28100000 {

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 = <&adsp>;
