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.
21 - realtek,reset-gpio : The GPIO that controls the CODEC's RESET pin. Active low.
23 - realtek,in1-differential
24 - realtek,in2-differential
25 - realtek,lout1-differential
26 - realtek,lout2-differential
27 - realtek,lout3-differential
28 Boolean. Indicate MIC1/2 input and LOUT1/2/3 outputs are differential,
29 rather than single-ended.
32 Array of six 8bit elements that configures GPIO.
33 0 - floating (reset value)
38 Configures GPIO Mic Jack detection 1.
39 Select 0 ~ 3 as OFF, GPIO1, GPIO2 and GPIO3 respectively.
43 Configures GPIO Mic Jack detection 2 and 3.
44 Select 0 ~ 3 as OFF, GPIO4, GPIO5 and GPIO6 respectively.
