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 - "ti,tas5733" 16- reg: The I2C address of the device 17- #sound-dai-cells: must be equal to 0 18 19Optional properties: 20 21- reset-gpios: GPIO specifier for the TAS571x's active low reset line 22- pdn-gpios: GPIO specifier for the TAS571x's active low powerdown line 23- clocks: clock phandle for the MCLK input 24- clock-names: should be "mclk" 25- AVDD-supply: regulator phandle for the AVDD supply (all chips) 26- DVDD-supply: regulator phandle for the DVDD supply (all chips) 27- HPVDD-supply: regulator phandle for the HPVDD supply (5717/5719) 28- PVDD_AB-supply: regulator phandle for the PVDD_AB supply (5717/5719) 29- PVDD_CD-supply: regulator phandle for the PVDD_CD supply (5717/5719) 30- PVDD_A-supply: regulator phandle for the PVDD_A supply (5711) 31- PVDD_B-supply: regulator phandle for the PVDD_B supply (5711) 32- PVDD_C-supply: regulator phandle for the PVDD_C supply (5711) 33- PVDD_D-supply: regulator phandle for the PVDD_D supply (5711) 34- DRVDD-supply: regulator phandle for the DRVDD supply (5721) 35- PVDD-supply: regulator phandle for the PVDD supply (5721) 36 37Example: 38 39 tas5717: audio-codec@2a { 40 compatible = "ti,tas5717"; 41 reg = <0x2a>; 42 #sound-dai-cells = <0>; 43 44 reset-gpios = <&gpio5 1 GPIO_ACTIVE_LOW>; 45 pdn-gpios = <&gpio5 2 GPIO_ACTIVE_LOW>; 46 47 clocks = <&clk_core CLK_I2S>; 48 clock-names = "mclk"; 49 }; 50
