+RT5659/RT5658 audio CODEC
+
+This device supports I2C only.
+
+Required properties:
+
+- compatible : One of "realtek,rt5659" or "realtek,rt5658".
+
+- reg : The I2C address of the device.
+
+- interrupts : The CODEC's interrupt output.
+
+Optional properties:
+
+- clocks: The phandle of the master clock to the CODEC
+- clock-names: Should be "mclk"
+
+- realtek,in1-differential
+- realtek,in3-differential
+- realtek,in4-differential
+ Boolean. Indicate MIC1/3/4 input are differential, rather than single-ended.
+
+- realtek,dmic1-data-pin
+ 0: dmic1 is not used
+ 1: using IN2N pin as dmic1 data pin
+ 2: using GPIO5 pin as dmic1 data pin
+ 3: using GPIO9 pin as dmic1 data pin
+ 4: using GPIO11 pin as dmic1 data pin
+
+- realtek,dmic2-data-pin
+ 0: dmic2 is not used
+ 1: using IN2P pin as dmic2 data pin
+ 2: using GPIO6 pin as dmic2 data pin
+ 3: using GPIO10 pin as dmic2 data pin
+ 4: using GPIO12 pin as dmic2 data pin
+
+- realtek,jd-src
+ 0: No JD is used
+ 1: using JD3 as JD source
+ 2: JD source for Intel HDA header
+
+- realtek,ldo1-en-gpios : The GPIO that controls the CODEC's LDO1_EN pin.
+- realtek,reset-gpios : The GPIO that controls the CODEC's RESET pin.
+
+- sound-name-prefix: Please refer to dai-common.yaml
+
+- ports: A Codec may have a single or multiple I2S interfaces. These
+ interfaces on Codec side can be described under 'ports' or 'port'.
+ When the SoC or host device is connected to multiple interfaces of
+ the Codec, the connectivity can be described using 'ports' property.
+ If a single interface is used, then 'port' can be used. The usage
+ depends on the platform or board design.
+ Please refer to Documentation/devicetree/bindings/graph.txt
+

+ realtek,ldo1-en-gpios =
+ <&gpio TEGRA_GPIO(V, 3) GPIO_ACTIVE_HIGH>;
