0015 SB Remote Management Interface (SB-RMI) is an SMBus compatible
0016 interface that reports AMD SoC's Power (normalized Power) using,
0017 Mailbox Service Request and resembles a typical 8-pin remote power
0018 sensor's I2C interface to BMC. The power attributes in hwmon
0019 reports power in microwatts.

0029 I2C bus address of the device as specified in Section SBI SMBus Address
0030 of the SoC register reference. The SB-RMI address is normally 78h for
0031 socket 0 and 70h for socket 1, but it could vary based on hardware
0032 address select pins.
