hwmon: Add support for SB-RMI power module
On AMD platforms the Out-of-band access is provided by
Advanced Platform Management Link (APML), APML is a
SMBus v2.0 compatible 2-wire processor client interface.
APML is also referred as the sideband interface (SBI).
APML is used to communicate with the
Side-Band Remote Management Interface (SB-RMI) which provides
Soft Mailbox messages to manage power consumption and
power limits of the CPU socket.
- This module add support to read power consumption,
power limit & max power limit and write power limit.
- To instantiate this driver on a Board Management Controller (BMC)
connected to an AMD CPU with SB-RMI support, the i2c bus number
would be the bus connected from the BMC to the CPU.
