+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.
+
+ Datasheet: The SB-TSI interface and protocol is available as part of
+ the open source SoC register reference at:
+
+ https://www.amd.com/system/files/TechDocs/56255_OSRR.pdf

+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.
