-* 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.
-
-Examples:
