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- realtek,reset-gpio : The GPIO that controls the CODEC's RESET pin. Active low.
22
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.
30
31- realtek,gpio-config
32  Array of six 8bit elements that configures GPIO.
33    0 - floating (reset value)
34    1 - pull down
35    2 - pull up
36
37- realtek,jd1-gpio
38  Configures GPIO Mic Jack detection 1.
39  Select 0 ~ 3 as OFF, GPIO1, GPIO2 and GPIO3 respectively.
40
41- realtek,jd2-gpio
42- realtek,jd3-gpio
43  Configures GPIO Mic Jack detection 2 and 3.
44  Select 0 ~ 3 as OFF, GPIO4, GPIO5 and GPIO6 respectively.
