RT1011 Mono Class D Audio Amplifier
This device supports I2C only.
Required properties:
- compatible : "realtek,rt1011".
- reg : The I2C address of the device. This I2C address decide by
two input pins (ASEL1 and ASEL2).
-------------------------------------
| ASEL2 | ASEL1 | Address |
-------------------------------------
| 0 | 0 | 0x38 |
-------------------------------------
| 0 | 1 | 0x39 |
-------------------------------------
| 1 | 0 | 0x3a |
-------------------------------------
| 1 | 1 | 0x3b |
-------------------------------------
Optional properties:
- realtek,temperature_calib
u32. The temperature was measured while doing the calibration. Units: Celsius degree
- realtek,r0_calib
u32. This is r0 calibration data which was measured in factory mode.
Pins on the device (for linking into audio routes) for RT1011:
* SPO
Example:
rt1011: codec@38 {
compatible = "realtek,rt1011";
reg = <0x38>;
realtek,temperature_calib = <25>;
realtek,r0_calib = <0x224050>;
};
