|
- reg - I2C slave address: it can be 0x40 if ADDR pin is 0
|
|
|
|
|
or 0x41 if ADDR pin is 1.

|
- 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.
