-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
-

-  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 name-prefix.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
-
