1RT5677 audio CODEC
2
3This device supports I2C only.
4
5Required properties:
6
7- compatible : "realtek,rt5677".
8
9- reg : The I2C address of the device.
10
11- interrupts : The CODEC's interrupt output.
12
13- gpio-controller : Indicates this device is a GPIO controller.
14
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).
17
18Optional properties:
19
20- realtek,pow-ldo2-gpio : The GPIO that controls the CODEC's POW_LDO2 pin.
21
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.
29
30- realtek,gpio-config
31  Array of six 8bit elements that configures GPIO.
32    0 - floating (reset value)
33    1 - pull down
34    2 - pull up
35
36- realtek,jd1-gpio
37  Configures GPIO Mic Jack detection 1.
38  Select 0 ~ 3 as OFF, GPIO1, GPIO2 and GPIO3 respectively.
39
40- realtek,jd2-gpio
41- realtek,jd3-gpio
42  Configures GPIO Mic Jack detection 2 and 3.
43  Select 0 ~ 3 as OFF, GPIO4, GPIO5 and GPIO6 respectively.
