3 This device supports I2C only.
7 - compatible : "realtek,rt5677".
9 - reg : The I2C address of the device.
11 - interrupts : The CODEC's interrupt output.
13 - gpio-controller : Indicates this device is a GPIO controller.
15 - #gpio-cells : Should be two. The first cell is the pin number and the
16 second cell is used to specify optional parameters (currently unused).
20 - realtek,pow-ldo2-gpio : The GPIO that controls the CODEC's POW_LDO2 pin.
22 - realtek,in1-differential
23 - realtek,in2-differential
24 - realtek,lout1-differential
25 - realtek,lout2-differential
26 - realtek,lout3-differential
27 Boolean. Indicate MIC1/2 input and LOUT1/2/3 outputs are differential,
28 rather than single-ended.
31 Array of six 8bit elements that configures GPIO.
32 0 - floating (reset value)
37 Configures GPIO Mic Jack detection 1.
38 Select 0 ~ 3 as OFF, GPIO1, GPIO2 and GPIO3 respectively.
42 Configures GPIO Mic Jack detection 2 and 3.
43 Select 0 ~ 3 as OFF, GPIO4, GPIO5 and GPIO6 respectively.
