RT5514 audio CODEC
This device supports I2C only.
This device supports both I2C and SPI.
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"
- realtek,dmic-init-delay-ms
Set the DMIC initial delay (ms) to wait it ready.
- interrupt-parent: The phandle for the interrupt controller.
- interrupts: The interrupt number to the cpu. The interrupt specifier format
depends on the interrupt controller.
Pins on the device (for linking into audio routes) for RT5514:
- 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
