Qualcomm WCD9335 Codec is a standalone Hi-Fi audio codec IC, supports
Qualcomm Technologies, Inc. (QTI) multimedia solutions, including
the MSM8996, MSM8976, and MSM8956 chipsets. It has in-build
Soundwire controller, interrupt mux. It supports both I2S/I2C and
SLIMbus audio interfaces.

+= WCD9335 Child devices
+Each subnode of WCD9335 represents a functional blocks like
+"audio codec", "soundwire Controller" of WCD. The name of the
+nodes are not important. The properties of these nodes are
+defined by the individual bindings for the specific device.
+
+Example:
+
+wcd9335@1 {
+ compatible = "slim217,1a0";
+ reg = <1 0>;
+ interrupts = <&msmgpio 54 IRQ_TYPE_LEVEL_HIGH>;
+ interrupt-names = "intr2"
+ reset-gpio = <&msmgpio 64 0>;
+ qcom,ifd = <&wc9335_ifd>;
+ clock-names = "mclk", "native";
+ clocks = <&rpmcc RPM_SMD_DIV_CLK1>,
+ <&rpmcc RPM_SMD_BB_CLK1>;
+ vdd-buck-supply = <&pm8994_s4>;
+ vdd-rx-supply = <&pm8994_s4>;
+ vdd-buck-sido-supply = <&pm8994_s4>;
+ vdd-tx-supply = <&pm8994_s4>;
+ vdd-io-supply = <&pm8994_s4>;
+
+ codec {
+ compatible = "qcom,wcd9335-codec";
+ #sound-dai-cells = <1>;
