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.

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.
