+* Qualcomm Technologies LPASS CPU DAI
+
+This node models the Qualcomm Technologies Low-Power Audio SubSystem.
+
+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"
+
+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";
