1 RT5651 audio CODEC
2
3 This device supports I2C only.
4
5 Required properties:
6
7 - compatible : "realtek,rt5651".
8
9 - reg : The I2C address of the device.
10
11 Optional 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
