1 | Texas Instruments - tas2552 Codec module |
| 2 | ||
| 3 | The tas2552 serial control bus communicates through I2C protocols | |
| 4 | ||
| 5 | Required properties: | |
| 6 | - compatible - One of: | |
| 7 | "ti,tas2552" - TAS2552 | |
| 8 | - reg - I2C slave address | |
| 9 | - supply-*: Required supply regulators are: | |
| 10 | "vbat" battery voltage | |
| 11 | "iovdd" I/O Voltage | |
| 12 | "avdd" Analog DAC Voltage | |
| 13 | ||
| 14 | Optional properties: | |
| 15 | - enable-gpio - gpio pin to enable/disable the device | |

17 | tas2552 can receive it's reference clock via MCLK, BCLK, IVCLKIN pin or use the |
| 18 | internal 1.8MHz. This CLKIN is used by the PLL. In addition to PLL, the PDM | |
| 19 | reference clock is also selectable: PLL, IVCLKIN, BCLK or MCLK. | |
| 20 | For system integration the dt-bindings/sound/tas2552.h header file provides | |
| 21 | defined values to selct and configure the PLL and PDM reference clocks. | |

23 | Example: |
| 24 | ||
| 25 | tas2552: tas2552@41 { | |
| 26 | compatible = "ti,tas2552"; | |
| 27 | reg = <0x41>; | |
| 28 | enable-gpio = <&gpio4 2 GPIO_ACTIVE_HIGH>; | |
| 29 | }; | |
