1ROHM BD28623MUV Class D speaker amplifier for digital input 2 3This codec does not have any control buses such as I2C, it detect format and 4rate of I2S signal automatically. It has two signals that can be connected 5to GPIOs: reset and mute. 6 7Required properties: 8- compatible : should be "rohm,bd28623" 9- #sound-dai-cells: should be 0. 10- VCCA-supply : regulator phandle for the VCCA supply 11- VCCP1-supply : regulator phandle for the VCCP1 supply 12- VCCP2-supply : regulator phandle for the VCCP2 supply 13 14Optional properties: 15- reset-gpios : GPIO specifier for the active low reset line 16- mute-gpios : GPIO specifier for the active low mute line 17 18Example: 19 20 codec { 21 compatible = "rohm,bd28623"; 22 #sound-dai-cells = <0>; 23 24 VCCA-supply = <&vcc_reg>; 25 VCCP1-supply = <&vcc_reg>; 26 VCCP2-supply = <&vcc_reg>; 27 reset-gpios = <&gpio 0 GPIO_ACTIVE_LOW>; 28 mute-gpios = <&gpio 1 GPIO_ACTIVE_LOW>; 29 }; 30
