Kernel-4.18.0-80.el8_rt5514

RT5514 audio CODEC

This device supports both I2C and SPI.

Required properties:

• 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
  Set the DMIC initial delay (ms) to wait it ready for I2C.

Pins on the device (for linking into audio routes) for I2C:

• DMIC1L
• DMIC1R
• DMIC2L
• DMIC2R
• AMICL
• AMICR

Example:

rt5514: codec@57 {
compatible = “realtek,rt5514”;
reg = <0x57>;
};
