      SB Temperature Sensor Interface (SB-TSI) is an SMBus compatible
      interface that reports AMD SoC's Ttcl (normalized temperature),
      and resembles a typical 8-pin remote temperature sensor's I2C interface
      to BMC. The emulated thermal sensor can report temperatures in increments
      of 0.125 degrees, ranging from 0 to 255.875.
    
    properties:
      compatible:
        enum:
          - amd,sbtsi
    
      reg:
        maxItems: 1
        description: |
          I2C bus address of the device as specified in Section 6.3.1 of the
          SoC register reference. The SB-TSI address is normally 98h for socket
          0 and 90h for socket 1, but it could vary based on hardware address
          select pins.
