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.
