+ES7241 i2s AD converter
+
+Required properties:
+- compatible : "everest,es7241"
+- VDDP-supply: regulator phandle for the VDDA supply
+- VDDA-supply: regulator phandle for the VDDP supply
+- VDDD-supply: regulator phandle for the VDDD supply
+
+Optional properties:
+- reset-gpios: gpio connected to the reset pin
+- m0-gpios : gpio connected to the m0 pin
+- m1-gpios : gpio connected to the m1 pin
+- everest,sdout-pull-down:
+ Format used by the serial interface is controlled by pulling
+ the sdout. If the sdout is pulled down, leftj format is used.
+ If this property is not provided, sdout is assumed to pulled
+ up and i2s format is used
+
+Example:
+
+linein: audio-codec@2 {
+ #sound-dai-cells = <0>;
+ compatible = "everest,es7241";
+ VDDA-supply = <&vcc_3v3>;
+ VDDP-supply = <&vcc_3v3>;
+ VDDD-supply = <&vcc_3v3>;
+ reset-gpios = <&gpio GPIOH_42>;
+};
