-Nuvoton NAU8315 Mono Class-D Amplifier

-Required properties:
-- compatible   : "nuvoton,nau8315"
-                 "nuvoton,nau8318"
-
-Optional properties:
-- enable-gpios : GPIO specifier for the chip's device enable input(EN) pin.
-        If this option is not specified then driver does not manage
-        the pin state (e.g. chip is always on).
-
-Example:
-
-#include <dt-bindings/gpio/gpio.h>
-
-nau8315 {
-	compatible = "nuvoton,nau8315";
-	enable-gpios = <&gpio1 5 GPIO_ACTIVE_HIGH>;
-};
-
-nau8318 {
-	compatible = "nuvoton,nau8318";
-	enable-gpios = <&gpio1 5 GPIO_ACTIVE_HIGH>;
-};
