This device supports both I2C and SPI.

- compatible : "realtek,rt5514".
- reg : the I2C address of the device for I2C, the chip select
number for SPI.
Optional properties:
- clocks: The phandle of the master clock to the CODEC
- clock-names: Should be "mclk"
- interrupt-parent: The phandle for the interrupt controller.
- interrupts: The interrupt number to the cpu. The interrupt specifier format
depends on the interrupt controller.
- realtek,dmic-init-delay-ms

* DMIC1L
* DMIC1R
* DMIC2L
* DMIC2R
* AMICL
* AMICR
Example:
