Kernel driver sbtsi_temp
========================
Supported hardware:
* Sideband interface (SBI) Temperature Sensor Interface (SB-TSI)
compliant AMD SoC temperature device.
Prefix: 'sbtsi_temp'
Addresses scanned: This driver doesn't support address scanning.
To instantiate this driver on an AMD CPU with SB-TSI
support, the i2c bus number would be the bus connected from the board
management controller (BMC) to the CPU. The i2c address is specified in
Section
6.
3.
1 of the SoC register reference: The SB-TSI address is normally
98h for socket
0 and
90h for socket
1, but it could vary based on hardware
address select pins.
Datasheet: The SB-TSI interface and protocol is available as part of
the open source SoC register reference at:

Description
-----------
The SBI temperature sensor interface (SB-TSI) is an emulation of the software
and physical interface of a typical
8-pin remote temperature sensor (RTS) on
AMD SoCs. It implements one temperature sensor with readings and limit
registers encode the temperature in increments of
0.
125 from
0 to
255.
875.
Limits can be set through the writable thresholds, and if reached will trigger
corresponding alert signals.
