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:
