+Kernel driver Ampere(R)'s Altra(R) SMpro hwmon
+==============================================
+
+Supported chips:
+
+ * Ampere(R) Altra(R)
+
+ Prefix: 'smpro'
+
+ Reference: Altra SoC BMC Interface Specification
+
+Author: Thu Nguyen <[email protected]>
+
+Description
+-----------
+This driver supports hardware monitoring for Ampere(R) Altra(R) SoC's based on the
+SMpro co-processor (SMpro).
+The following sensor types are supported by the driver:
+
+ * temperature
+ * voltage
+ * current
+ * power
+
+The SMpro interface provides the registers to query the various sensors and
+their values which are then exported to userspace by this driver.
+
+Usage Notes
+-----------
+
+SMpro hwmon driver creates at least two sysfs files for each sensor.
+
+* File ``<sensor_type><idx>_label`` reports the sensor label.
+* File ``<sensor_type><idx>_input`` returns the sensor value.
+
+The sysfs files are allocated in the SMpro root fs folder.
+There is one root folder for each SMpro instance.
+
+When the SoC is turned off, the driver will fail to read registers
+and return -ENXIO.
+
+Sysfs entries

+
+The following sysfs files are supported:
+
