1Texas Instruments TAS5711/TAS5717/TAS5719/TAS5721 stereo power amplifiers 2 3The codec is controlled through an I2C interface. It also has two other 4signals that can be wired up to GPIOs: reset (strongly recommended), and 5powerdown (optional). 6 7Required properties: 8 9- compatible: should be one of the following: 10 - "ti,tas5707" 11 - "ti,tas5711", 12 - "ti,tas5717", 13 - "ti,tas5719", 14 - "ti,tas5721" 15- reg: The I2C address of the device 16- #sound-dai-cells: must be equal to 0 17 18Optional properties: 19 20- reset-gpios: GPIO specifier for the TAS571x's active low reset line 21- pdn-gpios: GPIO specifier for the TAS571x's active low powerdown line 22- clocks: clock phandle for the MCLK input 23- clock-names: should be "mclk" 24- AVDD-supply: regulator phandle for the AVDD supply (all chips) 25- DVDD-supply: regulator phandle for the DVDD supply (all chips) 26- HPVDD-supply: regulator phandle for the HPVDD supply (5717/5719) 27- PVDD_AB-supply: regulator phandle for the PVDD_AB supply (5717/5719) 28- PVDD_CD-supply: regulator phandle for the PVDD_CD supply (5717/5719) 29- PVDD_A-supply: regulator phandle for the PVDD_A supply (5711) 30- PVDD_B-supply: regulator phandle for the PVDD_B supply (5711) 31- PVDD_C-supply: regulator phandle for the PVDD_C supply (5711) 32- PVDD_D-supply: regulator phandle for the PVDD_D supply (5711) 33- DRVDD-supply: regulator phandle for the DRVDD supply (5721) 34- PVDD-supply: regulator phandle for the PVDD supply (5721) 35 36Example: 37 38 tas5717: audio-codec@2a { 39 compatible = "ti,tas5717"; 40 reg = <0x2a>; 41 #sound-dai-cells = <0>; 42 43 reset-gpios = <&gpio5 1 GPIO_ACTIVE_LOW>; 44 pdn-gpios = <&gpio5 2 GPIO_ACTIVE_LOW>; 45 46 clocks = <&clk_core CLK_I2S>; 47 clock-names = "mclk"; 48 };
