1*4882a593SmuzhiyunRT5514 audio CODEC
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunThis device supports both I2C and SPI.
4*4882a593Smuzhiyun
5*4882a593SmuzhiyunRequired properties:
6*4882a593Smuzhiyun
7*4882a593Smuzhiyun- compatible : "realtek,rt5514".
8*4882a593Smuzhiyun
9*4882a593Smuzhiyun- reg : the I2C address of the device for I2C, the chip select
10*4882a593Smuzhiyun        number for SPI.
11*4882a593Smuzhiyun
12*4882a593SmuzhiyunOptional properties:
13*4882a593Smuzhiyun
14*4882a593Smuzhiyun- clocks: The phandle of the master clock to the CODEC
15*4882a593Smuzhiyun- clock-names: Should be "mclk"
16*4882a593Smuzhiyun
17*4882a593Smuzhiyun- interrupts: The interrupt number to the cpu. The interrupt specifier format
18*4882a593Smuzhiyun	      depends on the interrupt controller.
19*4882a593Smuzhiyun
20*4882a593Smuzhiyun- realtek,dmic-init-delay-ms
21*4882a593Smuzhiyun  Set the DMIC initial delay (ms) to wait it ready for I2C.
22*4882a593Smuzhiyun
23*4882a593SmuzhiyunPins on the device (for linking into audio routes) for I2C:
