1 RT5650/RT5645 audio CODEC
3 This device supports I2C only.
7 - compatible : One of "realtek,rt5645" or "realtek,rt5650".
9 - reg : The I2C address of the device.
11 - interrupts : The CODEC's interrupt output.
16 a GPIO spec for the external headphone detect pin. If jd-mode = 0,
17 we will get the JD status by getting the value of hp-detect-gpios.
19 - realtek,in2-differential
20 Boolean. Indicate MIC2 input are differential, rather than single-ended.
22 - realtek,dmic1-data-pin
24 1: using IN2P pin as dmic1 data pin
25 2: using GPIO6 pin as dmic1 data pin
26 3: using GPIO10 pin as dmic1 data pin
27 4: using GPIO12 pin as dmic1 data pin
29 - realtek,dmic2-data-pin
31 1: using IN2N pin as dmic2 data pin
32 2: using GPIO5 pin as dmic2 data pin
33 3: using GPIO11 pin as dmic2 data pin
35 -- realtek,jd-mode : The JD mode of rt5645/rt5650
36 0 : rt5645/rt5650 JD function is not used
37 1 : Mode-0 (VDD=3.3V), two port jack detection
38 2 : Mode-1 (VDD=3.3V), one port jack detection
39 3 : Mode-2 (VDD=1.8V), one port jack detection
