| Texas Instruments TAS5760 General purpose class-D amplifier. |
| |
| The codec is controlled through and I2C interface. It also has an optional |
| speaker shutdown(SPK_SD) signal which can be wired to a GPIO. |
| |
| Required properties: |
| |
| - compatible: "ti, tas5760" |
| - reg : The I2C address of the device |
| - #sound-dai-cells: must be equal to 0 |
| |
| Optional properties: |
| |
| - spk-sd-gpios: GPIO specifier for TAS5760's active low speaker shutdown line |
| - hw_params: subnode to specify the config parameters used for initialisation |
| of chip. It consists of the following optional properties: |
| - pbtl-mode: selection for PBTL/BTL mode |
| - pbtl-right-channel: channel selection for PBTL mode |
| - volume-fading: enable/disable volume fading |
| - digital-clip: value for adjusting digital clip level |
| range: (0 to 0xFFFFF) |
| - digital-boost: digital gain of the amplifier |
| possible values(dB): 0,6,12,18 |
| - analog-gain: value for adjusting analog gain of the amplifier |
| possible values(0.1 dBV): 192, 226, 250 |
| - pwm-rate: control for pwm output swtching rate |
| range: (0 to 7) |
| |
| Example: |
| tas5760@06c { |
| compatible: "ti,tas5760"; |
| reg = <0x6c>; |
| #sound-dai-cells = <0>; |
| |
| spk-sd-gpios = <&gpio1 5 GPIO_ACTIVE_LOW>; |
| |
| hw_params { |
| pbtl-mode; |
| pbtl-right-channel; |
| digital-clip = <0XFFFFF>; |
| volume-fading; |
| digital-boost = <6>; |
| analog-gain = <192>; |
| pwm-rate = <5>; |
| }; |
| }; |
