PCM512x audio CODECs
|
||||
|
||||
These devices support both I2C and SPI (configured with pin strapping
|
||||
on the board).
|
||||
|
||||
Required properties:
|
||||
|
||||
- compatible : One of "ti,pcm5121" or "ti,pcm5122"
|
||||
|
||||
- reg : the I2C address of the device for I2C, the chip select
|
||||
number for SPI.
|
||||
|
||||
- AVDD-supply, DVDD-supply, and CPVDD-supply : power supplies for the
|
||||
device, as covered in bindings/regulator/regulator.txt
|
||||
|
||||
Optional properties:
|
||||
|
||||
- clocks : A clock specifier for the clock connected as SCLK. If this
|
||||
is absent the device will be configured to clock from BCLK.
|
||||
|
||||
Example:
|
||||
|
||||
pcm5122: pcm5122@4c {
|
||||
compatible = "ti,pcm5122";
|
||||
reg = <0x4c>;
|
||||
|
||||
AVDD-supply = <®_3v3_analog>;
|
||||
DVDD-supply = <®_1v8>;
|
||||
CPVDD-supply = <®_3v3>;
|
||||
};
