     1 RT5650/RT5645 audio CODEC
    2 
    3 This device supports I2C only.
    4 
    5 Required properties:
    6 
    7 - compatible : One of "realtek,rt5645" or "realtek,rt5650".
    8 
    9 - reg : The I2C address of the device.
   10 
   11 - interrupts : The CODEC's interrupt output.
   12 
   13 - avdd-supply: Power supply for AVDD, providing 1.8V.
   14 
   15 - cpvdd-supply: Power supply for CPVDD, providing 3.5V.
   16 
   17 Optional properties:
   18 
   19 - hp-detect-gpios:
   20   a GPIO spec for the external headphone detect pin. If jd-mode = 0,
   21   we will get the JD status by getting the value of hp-detect-gpios.
   22 
   23 - realtek,in2-differential
   24   Boolean. Indicate MIC2 input are differential, rather than single-ended.
   25 
   26 - realtek,dmic1-data-pin
   27   0: dmic1 is not used
   28   1: using IN2P pin as dmic1 data pin
   29   2: using GPIO6 pin as dmic1 data pin
   30   3: using GPIO10 pin as dmic1 data pin
   31   4: using GPIO12 pin as dmic1 data pin
   32 
   33 - realtek,dmic2-data-pin
   34   0: dmic2 is not used
   35   1: using IN2N pin as dmic2 data pin
   36   2: using GPIO5 pin as dmic2 data pin
   37   3: using GPIO11 pin as dmic2 data pin
   38 
   39 -- realtek,jd-mode : The JD mode of rt5645/rt5650
   40    0 : rt5645/rt5650 JD function is not used
   41    1 : Mode-0 (VDD=3.3V), two port jack detection
   42    2 : Mode-1 (VDD=3.3V), one port jack detection
   43    3 : Mode-2 (VDD=1.8V), one port jack detection
