ROHM BD28623MUV Class D speaker amplifier for digital input
|
|
|
|
This codec does not have any control buses such as I2C, it detect format and
|
|
rate of I2S signal automatically. It has two signals that can be connected
|
|
to GPIOs: reset and mute.
|
|
|
|
Required properties:
|
|
- compatible : should be "rohm,bd28623"
|
|
- #sound-dai-cells: should be 0.
|
|
- VCCA-supply : regulator phandle for the VCCA supply
|
|
- VCCP1-supply : regulator phandle for the VCCP1 supply
|
|
- VCCP2-supply : regulator phandle for the VCCP2 supply
|
|
|
|
Optional properties:
|
|
- reset-gpios : GPIO specifier for the active low reset line
|
|
- mute-gpios : GPIO specifier for the active low mute line
|
|
|
|
Example:
|
|
|
|
codec {
|
|
compatible = "rohm,bd28623";
|
|
#sound-dai-cells = <0>;
|
|
|
|
VCCA-supply = <&vcc_reg>;
|
|
VCCP1-supply = <&vcc_reg>;
|
|
VCCP2-supply = <&vcc_reg>;
|
|
reset-gpios = <&gpio 0 GPIO_ACTIVE_LOW>;
|
|
mute-gpios = <&gpio 1 GPIO_ACTIVE_LOW>;
|
|
};
