Required properties:



- compatible : "realtek,rt5514".



- reg : The I2C address of the device.

- 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

  Set the DMIC initial delay (ms) to wait it ready.
