1Texas Instruments - tas2552 Codec module 2 3The tas2552 serial control bus communicates through I2C protocols 4 5Required 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 14Optional properties: 15 - enable-gpio - gpio pin to enable/disable the device 16 17tas2552 can receive it's reference clock via MCLK, BCLK, IVCLKIN pin or use the 18internal 1.8MHz. This CLKIN is used by the PLL. In addition to PLL, the PDM 19reference clock is also selectable: PLL, IVCLKIN, BCLK or MCLK. 20For system integration the dt-bindings/sound/tas2552.h header file provides 21defined values to selct and configure the PLL and PDM reference clocks. 22 23Example: 24 25tas2552: tas2552@41 { 26 compatible = "ti,tas2552"; 27 reg = <0x41>; 28 enable-gpio = <&gpio4 2 GPIO_ACTIVE_HIGH>; 29}; 30 31For more product information please see the link below: 32http://www.ti.com/product/TAS2552 33
