* 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"
Optional properties:
- qcom,adsp : Phandle for the audio DSP node
Example:
lpass@28100000 {
compatible = "qcom,lpass-cpu";

Renesas Sampling Rate Convert Sound Card:
Renesas Sampling Rate Convert Sound Card specifies audio DAI connections of SoC <-> codec.
Required properties:
- compatible : "renesas,rsrc-card,<board>"
Examples with soctypes are:
- "renesas,rsrc-card,lager"
- "renesas,rsrc-card,koelsch"
Optional properties:
- card_name : User specified audio sound card name, one string
property.
- cpu : CPU sub-node
- codec : CODEC sub-node
Optional subnode properties:
- format : CPU/CODEC common audio format.
"i2s", "right_j", "left_j" , "dsp_a"
"dsp_b", "ac97", "pdm", "msb", "lsb"
- frame-master : Indicates dai-link frame master.
phandle to a cpu or codec subnode.
- bitclock-master : Indicates dai-link bit clock master.
phandle to a cpu or codec subnode.
- bitclock-inversion : bool property. Add this if the
dai-link uses bit clock inversion.
- frame-inversion : bool property. Add this if the
dai-link uses frame clock inversion.
- convert-rate : platform specified sampling rate convert
Required CPU/CODEC subnodes properties:
- sound-dai : phandle and port of CPU/CODEC
Optional CPU/CODEC subnodes properties:
- clocks / system-clock-frequency : specify subnode's clock if needed.
it can be specified via "clocks" if system has
clock node (= common clock), or "system-clock-frequency"
(if system doens't support common clock)
If a clock is specified, it is
enabled with clk_prepare_enable()
in dai startup() and disabled with
clk_disable_unprepare() in dai
shutdown().
Example
sound {
compatible = "renesas,rsrc-card,lager";
card-name = "rsnd-ak4643";
format = "left_j";
bitclock-master = <&sndcodec>;
frame-master = <&sndcodec>;
sndcpu: cpu {
sound-dai = <&rcar_sound>;
};
sndcodec: codec {
sound-dai = <&ak4643>;
system-clock-frequency = <11289600>;
};

* Sound complex for Storm boards
Models a soundcard for Storm boards with the Qualcomm Technologies IPQ806x SOC
connected to a MAX98357A DAC via I2S.
Required properties:
- compatible : "google,storm-audio"
- cpu : Phandle of the CPU DAI
- codec : Phandle of the codec DAI
Optional properties:
- qcom,model : The user-visible name of this sound card.
Example:
