Subject: [PATCH 1/2] dt-bindings: sound: Add bindings for UDA1334 codec
Date: Wed, 31 Jul 2019 14:19:29 +0300 [thread overview]
Message-ID: <20190731111930.20230-2-andradanciu1997@gmail.com> (raw)
In-Reply-To: <20190731111930.20230-1-andradanciu1997@gmail.com>
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>;
+};
