-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>;
