   15   SB Remote Management Interface (SB-RMI) is an SMBus compatible
   16   interface that reports AMD SoC's Power (normalized Power) using,
   17   Mailbox Service Request and resembles a typical 8-pin remote power
   18   sensor's I2C interface to BMC. The power attributes in hwmon
   19   reports power in microwatts.

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