* 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" or
|
||||
"qcom,sc7180-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"
|
||||
: required clocks for "qcom,lpass-cpu-sc7180"
|
||||
* "audio-core"
|
||||
* "mclk0"
|
||||
* "mi2s-bit-clk0"
|
||||
* "mi2s-bit-clk1"
|
||||
* "pcnoc-sway-clk"
|
||||
* "pcnoc-mport-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"
|
||||
- #address-cells : Must be 1
|
||||
- #size-cells : Must be 0
|
||||
|
||||
|
||||
|
||||
Optional properties:
|
||||
|
||||
- qcom,adsp : Phandle for the audio DSP node
|
||||
|
||||
By default, the driver uses up to 4 MI2S SD lines, for a total of 8 channels.
|
||||
The SD lines to use can be configured by adding subnodes for each of the DAIs.
|
||||
|
||||
Required properties for each DAI (represented by a subnode):
|
||||
- reg : Must be one of the DAI IDs
|
||||
(usually part of dt-bindings header)
|
||||
- qcom,playback-sd-lines: List of serial data lines to use for playback
|
||||
Each SD line should be represented by a number from 0-3.
|
||||
- qcom,capture-sd-lines : List of serial data lines to use for capture
|
||||
Each SD line should be represented by a number from 0-3.
|
||||
|
||||
Note that adding a subnode changes the default to "no lines configured",
|
||||
so both playback and capture lines should be configured when a subnode is added.
|
||||

||||
