    1 RT5665/RT5666 audio CODEC
    2 
    3 This device supports I2C only.
    4 
    5 Required properties:
    6 
    7 - compatible : One of "realtek,rt5665", "realtek,rt5666".
    8 
    9 - reg : The I2C address of the device.
   10 
   11 - interrupts : The CODEC's interrupt output.
   12 
   13 Optional properties:
   14 
   15 - realtek,in1-differential
   16 - realtek,in2-differential
   17 - realtek,in3-differential
   18 - realtek,in4-differential
   19   Boolean. Indicate MIC1/2/3/4 input are differential, rather than single-ended.
   20 
   21 - realtek,dmic1-data-pin

   32   0: No JD is used
   33   1: using JD1 as JD source
   34 
   35 - realtek,ldo1-en-gpios : The GPIO that controls the CODEC's LDO1_EN pin.
