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.
23
-
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
-
};
