The UDA1334 is an NXP audio codec, supports the I2S-bus data format
and has basic features such as de-emphasis (at 44.1 kHz sampling
rate) and mute. Product information can be found at:

+UDA1334 audio CODEC
+
+This device uses simple GPIO pins for controlling codec settings.
+
+Required properties:
+
+  - compatible : "nxp,uda1334"
+  - nxp,mute-gpios: a GPIO spec for the MUTE pin.
+  - nxp,deemph-gpios: a GPIO spec for the De-emphasis pin
+
+Example:
+
+uda1334: audio-codec {
+	compatible = "nxp,uda1334";
+	nxp,mute-gpios = <&gpio1 8 GPIO_ACTIVE_LOW>;
+	nxp,deemph-gpios = <&gpio3 3 GPIO_ACTIVE_LOW>;
+};
