Subject: [PATCH] ASoC: Add ADAU7002 Stereo PDM-to-I2S/TDM Converter DT
bindings
The ADAU7002 takes a stereo PDM signal (e.g. from two digital microphones)
and converts it into a I2S/TDM PCM stream. The chip does not have a
control interface and has a single power supply that is modeled in the
devicetree.

+
+Required properties:
+
+ - compatible: Must be "adi,adau7002"
+
+Optional properties:
+
+ - IOVDD-supply: Phandle and specifier for the power supply providing the IOVDD
+ supply as covered in Documentation/devicetree/bindings/regulator/regulator.txt
+
+ If this property is not present it is assumed that the supply pin is
+ hardwired to always on.
+
+Example:
+ adau7002: pdm-to-i2s {
+ compatible = "adi,adau7002";
+ IOVDD-supply = <&supply>;
+ };
