    description: |
      SB Remote Management Interface (SB-RMI) is an SMBus compatible
      interface that reports AMD SoC's Power (normalized Power) using,
      Mailbox Service Request and resembles a typical 8-pin remote power
      sensor's I2C interface to BMC. The power attributes in hwmon
      reports power in microwatts.
    
    properties:
      compatible:
        enum:
          - amd,sbrmi
    
      reg:

        description: |
          I2C bus address of the device as specified in Section SBI SMBus Address
          of the SoC register reference. The SB-RMI address is normally 78h for
          socket 0 and 70h for socket 1, but it could vary based on hardware
          address select pins.
