-* 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"
-- #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.
-
-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";
- qcom,adsp = <&adsp>;
-
- #address-cells = <1>;
- #size-cells = <0>;
-
- /* Optional to set different MI2S SD lines */
- dai@3 {
- reg = <MI2S_QUATERNARY>;
- qcom,playback-sd-lines = <0 1>;
- };
-};
