    1 RT5514 audio CODEC
    2 
    3 This device supports both I2C and SPI.
    4 
    5 Required 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 
   12 Optional 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 
   23 Pins on the device (for linking into audio routes) for I2C:
   24 
   25   * DMIC1L
   26   * DMIC1R
   27   * DMIC2L
   28   * DMIC2R
   29   * AMICL
   30   * AMICR
   31 
   32 Example:
   33 
   34 rt5514: codec@57 {
   35         compatible = "realtek,rt5514";
   36         reg = <0x57>;
   37 };
