1RT5651 audio CODEC
2
3This device supports I2C only.
4
5Required properties:
6
7- compatible : "realtek,rt5651".
8
9- reg : The I2C address of the device.
10
11Optional properties:
12
13- realtek,in2-differential
14  Boolean. Indicate MIC2 input are differential, rather than single-ended.
15
16- realtek,dmic-en
17  Boolean. true if dmic is used.
18
19- realtek,jack-detect-source
20  u32. Valid values:
21  1: Use JD1_1 pin for jack-detect
22  2: Use JD1_2 pin for jack-detect
23  3: Use JD2 pin for jack-detect
24
25- realtek,jack-detect-not-inverted
26  bool. Normal jack-detect switches give an inverted (active-low) signal,
27  set this bool in the rare case you've a jack-detect switch which is not
28  inverted.
29
30- realtek,over-current-threshold-microamp
31  u32, micbias over-current detection threshold in µA, valid values are
32  600, 1500 and 2000µA.
33
34- realtek,over-current-scale-factor
35  u32, micbias over-current detection scale-factor, valid values are:
36  0: Scale current by 0.5
37  1: Scale current by 0.75
38  2: Scale current by 1.0
39  3: Scale current by 1.5
