1 RT5640/RT5639 audio CODEC
3 This device supports I2C only.
7 - compatible : One of "realtek,rt5640" or "realtek,rt5639".
9 - reg : The I2C address of the device.
11 - interrupts : The CODEC's interrupt output.
15 - clocks: The phandle of the master clock to the CODEC
16 - clock-names: Should be "mclk"
18 - realtek,in1-differential
19 - realtek,in2-differential
20 - realtek,in3-differential
21 Boolean. Indicate MIC1/2/3 input are differential, rather than single-ended.
23 - realtek,lout-differential
24 Boolean. Indicate LOUT output is differential, rather than stereo.
26 - realtek,ldo1-en-gpios : The GPIO that controls the CODEC's LDO1_EN pin.
28 - realtek,dmic1-data-pin
30 1: using IN1P pin as dmic1 data pin
31 2: using GPIO3 pin as dmic1 data pin
33 - realtek,dmic2-data-pin
35 1: using IN1N pin as dmic2 data pin
36 2: using GPIO4 pin as dmic2 data pin
38 - realtek,jack-detect-source
40 0: jack-detect is not used
41 1: Use GPIO1 for jack-detect
42 2: Use JD1_IN4P for jack-detect
43 3: Use JD2_IN4N for jack-detect
44 4: Use GPIO2 for jack-detect
45 5: Use GPIO3 for jack-detect
46 6: Use GPIO4 for jack-detect
48 - realtek,jack-detect-not-inverted
49 bool. Normal jack-detect switches give an inverted signal, set this bool
50 in the rare case you've a jack-detect switch which is not inverted.
52 - realtek,over-current-threshold-microamp
53 u32, micbias over-current detection threshold in µA, valid values are
56 - realtek,over-current-scale-factor
57 u32, micbias over-current detection scale-factor, valid values are:
58 0: Scale current by 0.5
59 1: Scale current by 0.75
60 2: Scale current by 1.0
61 3: Scale current by 1.5
