1RT5514 audio CODEC
2
3This device supports both I2C and SPI.
4
5Required properties:
6
7- compatible : "realtek,rt5514".
8
9- reg : the I2C address of the device for I2C, the chip select
10        number for SPI.
11
12Optional properties:
13
14- clocks: The phandle of the master clock to the CODEC
15- clock-names: Should be "mclk"
16
17- interrupts: The interrupt number to the cpu. The interrupt specifier format
18	      depends on the interrupt controller.
19
20- realtek,dmic-init-delay-ms
21  Set the DMIC initial delay (ms) to wait it ready for I2C.
22
23Pins on the device (for linking into audio routes) for I2C:
