      1RT5659/RT5658 audio CODEC
      2
      3This device supports I2C only.
      4
      5Required properties:
      6
      7- compatible : One of "realtek,rt5659" or "realtek,rt5658".
      8
      9- reg : The I2C address of the device.
     10
     11- interrupts : The CODEC's interrupt output.
     12
     13Optional properties:
     14
     15- clocks: The phandle of the master clock to the CODEC
     16- clock-names: Should be "mclk"
     17
     18- realtek,in1-differential
     19- realtek,in3-differential
     20- realtek,in4-differential
     21  Boolean. Indicate MIC1/3/4 input are differential, rather than single-ended.
     22
     23- realtek,dmic1-data-pin
     24  0: dmic1 is not used
     25  1: using IN2N pin as dmic1 data pin
     26  2: using GPIO5 pin as dmic1 data pin
     27  3: using GPIO9 pin as dmic1 data pin
     28  4: using GPIO11 pin as dmic1 data pin
     29
     30- realtek,dmic2-data-pin
     31  0: dmic2 is not used
     32  1: using IN2P pin as dmic2 data pin
     33  2: using GPIO6 pin as dmic2 data pin
     34  3: using GPIO10 pin as dmic2 data pin
     35  4: using GPIO12 pin as dmic2 data pin
     36
     37- realtek,jd-src
     38  0: No JD is used
     39  1: using JD3 as JD source
     40  2: JD source for Intel HDA header
     41
     42- realtek,ldo1-en-gpios : The GPIO that controls the CODEC's LDO1_EN pin.
     43- realtek,reset-gpios : The GPIO that controls the CODEC's RESET pin.
     44
     45- sound-name-prefix: Please refer to name-prefix.yaml
     46
     47- ports: A Codec may have a single or multiple I2S interfaces. These
     48  interfaces on Codec side can be described under 'ports' or 'port'.
     49  When the SoC or host device is connected to multiple interfaces of
     50  the Codec, the connectivity can be described using 'ports' property.
     51  If a single interface is used, then 'port' can be used. The usage
     52  depends on the platform or board design.
     53  Please refer to Documentation/devicetree/bindings/graph.txt
