* Qualcomm Technologies LPASS CPU DAI
|
|
|
|
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.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"
|
|
|
|
Required subnodes:
|
|
|
|
- qcom,adsp : Audio DSP sub-node
|
|
|
|
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";
|
|
