    1 RT1011 Mono Class D Audio Amplifier
    2 
    3 This device supports I2C only.
    4 
    5 Required properties:
    6 
    7 - compatible : "realtek,rt1011".
    8 
    9 - reg : The I2C address of the device. This I2C address decide by
   10         two input pins (ASEL1 and ASEL2).
   11         -------------------------------------
   12         |   ASEL2   |  ASEL1   |  Address   |
   13         -------------------------------------
   14         |     0     |    0     |   0x38     |
   15         -------------------------------------
   16         |     0     |    1     |   0x39     |

   21         -------------------------------------
   22 
   23 Optional properties:
   24 
   25 - realtek,temperature_calib
   26   u32. The temperature was measured while doing the calibration. Units: Celsius degree
   27 
   28 - realtek,r0_calib
   29   u32. This is r0 calibration data which was measured in factory mode.
   30 
   31 Pins on the device (for linking into audio routes) for RT1011:

   33   * SPO
   34 
   35 Example:
   36 
   37 rt1011: codec@38 {
   38         compatible = "realtek,rt1011";
   39         reg = <0x38>;
   40         realtek,temperature_calib = <25>;
   41         realtek,r0_calib = <0x224050>;
   42 };
