3 This device supports I2C only.
7 - compatible : "realtek,rt5640".
9 - reg : The I2C address of the device.
11 - interrupts : The CODEC's interrupt output.
15 - realtek,in1-differential
16 - realtek,in2-differential
17 Boolean. Indicate MIC1/2 input are differential, rather than single-ended.
19 - realtek,ldo1-en-gpios : The GPIO that controls the CODEC's LDO1_EN pin.
