Texas Instruments - tas2552 Codec module
|
|
|
|
|
|
|
|
|
|
The tas2552 serial control bus communicates through I2C protocols
|
|
|
|
|
|
|
|
|
|
Required properties:
|
|
|
|
|
- compatible - One of:
|
|
|
|
|
"ti,tas2552" - TAS2552
|
|
|
|
|
- reg - I2C slave address
|
|
|
|
|
- supply-*: Required supply regulators are:
|
|
|
|
|
"vbat" battery voltage
|
|
|
|
|
"iovdd" I/O Voltage
|
|
|
|
|
"avdd" Analog DAC Voltage
|
|
|
|
|
|
|
|
|
|
Optional properties:
|
|
|
|
|
- enable-gpio - gpio pin to enable/disable the device

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