An integrated on-chip DSP supports Texas17 Instruments Smart Amp speaker protection algorithm. The18 integrated speaker voltage and current sense provides for real time19 monitoring of loudspeaker behavior.20 21 Specifications about the audio amplifier can be found at:22 https://www.ti.com/lit/gpn/tas256323 https://www.ti.com/lit/gpn/tas278124 25properties:26 compatible:27 description: |28 ti,tas2563: 6.1-W Boosted Class-D Audio Amplifier With Integrated29 DSP and IV Sense, 16/20/24/32bit stereo I2S or multichannel TDM.30 31 ti,tas2781: 24-V Class-D Amplifier with Real Time Integrated Speaker32 Protection and Audio Processing, 16/20/24/32bit stereo I2S or33 multichannel TDM.34 oneOf:35 - items:36 - enum:37 - ti,tas256338 - const: ti,tas278139 - enum:40 - ti,tas278141 42 reg:43 description:44 I2C address, in multiple-AMP case, all the i2c address45 aggregate as one Audio Device to support multiple audio slots.46 maxItems: 847 minItems: 148 49 reset-gpios:50 maxItems: 151 52 interrupts:53 maxItems: 154 55 '#sound-dai-cells':56 const: 057 58required:59 - compatible60 - reg61 62allOf:63 - $ref: dai-common.yaml#64 - if:65 properties:66 compatible:67 contains:68 enum:69 - ti,tas256370 then:71 properties:72 reg:73 description:74 I2C address, in multiple-AMP case, all the i2c address75 aggregate as one Audio Device to support multiple audio slots.76 maxItems: 477 minItems: 178 items:79 minimum: 0x4c80 maximum: 0x4f81 82 - if:83 properties:84 compatible:85 contains:86 enum:87 - ti,tas278188 then:89 properties:90 reg:91 description:92 I2C address, in multiple-AMP case, all the i2c address93 aggregate as one Audio Device to support multiple audio slots.94 maxItems: 895 minItems: 196 items:97 minimum: 0x3898 maximum: 0x3f99 100additionalProperties: false101 102examples:103 - |104 #include <dt-bindings/gpio/gpio.h>105 i2c {106 /* example with quad tas2781s, such as tablet or pad device */107 #address-cells = <1>;108 #size-cells = <0>;109 quad_tas2781: tas2781@38 {110 compatible = "ti,tas2781";111 reg = <0x38>, /* Audio slot 0 */112 <0x3a>, /* Audio slot 1 */113 <0x39>, /* Audio slot 2 */114 <0x3b>; /* Audio slot 3 */115 116 #sound-dai-cells = <0>;117 reset-gpios = <&gpio1 10 GPIO_ACTIVE_HIGH>;118 interrupt-parent = <&gpio1>;119 interrupts = <15>;120 };121 };122...123
