This device supports I2C only.
Required properties:
- compatible : "realtek,alc5631" or "realtek,rt5631"
- reg : the I2C address of the device.
Pins on the device (for linking into audio routes):

* SPK_OUT_R_N
* SPK_OUT_L_P
* SPK_OUT_L_N
* HP_OUT_L
* HP_OUT_R
* AUX_OUT2_LP

* MIC1_P
* MIC1_N
* MIC2_P
* MIC2_N
* MONO_OUT_P
* MONO_OUT_N
* MICBIAS1
* MICBIAS2
Example:
alc5631: alc5631@1a {
compatible = "realtek,alc5631";
