PCM512x audio CODECs
|
|
|
|
These devices support both I2C and SPI (configured with pin strapping
|
|
on the board).
|
|
|
|
Required properties:
|
|
|
|
- compatible : One of "ti,pcm5121", "ti,pcm5122", "ti,pcm5141" or
|
|
"ti,pcm5142"
|
|
|
|
- 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. If pll-in
|
|
and pll-out are specified in addition to a clock, the device is
|
|
configured to accept clock input on a specified gpio pin.
|
|
|
|
- pll-in, pll-out : gpio pins used to connect the pll using <1>
|
|
through <6>. The device will be configured for clock input on the
|
|
given pll-in pin and PLL output on the given pll-out pin. An
|
|
external connection from the pll-out pin to the SCLK pin is assumed.
|
|
|
|
Examples:
|
|
|
|
pcm5122: pcm5122@4c {
|
|
compatible = "ti,pcm5122";
|
|
reg = <0x4c>;
|
|
|
|
AVDD-supply = <®_3v3_analog>;
|
|
DVDD-supply = <®_1v8>;
|
|
CPVDD-supply = <®_3v3>;
|
|
};
|
|
|
|
|
|
pcm5142: pcm5142@4c {
|
|
compatible = "ti,pcm5142";
|
|
reg = <0x4c>;
|
|
|
|
AVDD-supply = <®_3v3_analog>;
|
|
DVDD-supply = <®_1v8>;
|
|
CPVDD-supply = <®_3v3>;
|
|
|
|
clocks = <&sck>;
|
|
pll-in = <3>;
|
|
pll-out = <6>;
|
|
};
