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: it can be 0x40 if ADDR pin is 0
9 or 0x41 if ADDR pin is 1.
10 - supply-*: Required supply regulators are:
11 "vbat" battery voltage
12 "iovdd" I/O Voltage
13 "avdd" Analog DAC Voltage
14
15 Optional properties:
16 - enable-gpio - gpio pin to enable/disable the device
17
18 tas2552 can receive its reference clock via MCLK, BCLK, IVCLKIN pin or use the
19 internal 1.8MHz. This CLKIN is used by the PLL. In addition to PLL, the PDM
20 reference clock is also selectable: PLL, IVCLKIN, BCLK or MCLK.
21 For system integration the dt-bindings/sound/tas2552.h header file provides
22 defined values to select and configure the PLL and PDM reference clocks.

24 Example:
25
26 tas2552: tas2552@41 {
27 compatible = "ti,tas2552";
28 reg = <0x41>;
29 vbat-supply = <®_vbat>;
30 iovdd-supply = <®_iovdd>;
31 avdd-supply = <®_avdd>;
32 enable-gpio = <&gpio4 2 GPIO_ACTIVE_HIGH>;
33 };
