The PCM512x devices are a family of monolithic CMOS integrated circuits that include a stereo digital-to-analog converter and additional support circuitry. This is an initial driver which supports some core functionality for the device which covers common use cases but does not cover all features. Currently only slave clocking modes with automatic clock configuration are supported and most of the DSP configuration for the device is not enabled. Signed-off-by: Mark Brown <broonie@linaro.org>

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>;
|
|
};
