+Description
+-----------
+
+This driver implements a generic PECI hwmon feature which provides Digital
+Thermal Sensor (DTS) thermal readings of the CPU package and CPU cores that are
+accessible via the processor PECI interface.
+
+All temperature values are given in millidegree Celsius and will be measurable
+only when the target CPU is powered on.
+
+Sysfs interface

+======================= =======================================================
+temp1_label "Die"
+temp1_input Provides current die temperature of the CPU package.
+temp1_max Provides thermal control temperature of the CPU package
+ which is also known as Tcontrol.
+temp1_crit Provides shutdown temperature of the CPU package which
+ is also known as the maximum processor junction
+ temperature, Tjmax or Tprochot.
+temp1_crit_hyst Provides the hysteresis value from Tcontrol to Tjmax of
+ the CPU package.
+
+temp2_label "DTS"
+temp2_input Provides current temperature of the CPU package scaled
+ to match DTS thermal profile.
+temp2_max Provides thermal control temperature of the CPU package
+ which is also known as Tcontrol.
+temp2_crit Provides shutdown temperature of the CPU package which
+ is also known as the maximum processor junction
+ temperature, Tjmax or Tprochot.
+temp2_crit_hyst Provides the hysteresis value from Tcontrol to Tjmax of
+ the CPU package.
+
+temp3_label "Tcontrol"
+temp3_input Provides current Tcontrol temperature of the CPU
+ package which is also known as Fan Temperature target.
+ Indicates the relative value from thermal monitor trip
+ temperature at which fans should be engaged.
+temp3_crit Provides Tcontrol critical value of the CPU package
+ which is same to Tjmax.
+
+temp4_label "Tthrottle"
+temp4_input Provides current Tthrottle temperature of the CPU
+ package. Used for throttling temperature. If this value
+ is allowed and lower than Tjmax - the throttle will
+ occur and reported at lower than Tjmax.
+
+temp5_label "Tjmax"
+temp5_input Provides the maximum junction temperature, Tjmax of the
+ CPU package.
+
+temp[6-N]_label Provides string "Core X", where X is resolved core
+ number.
+temp[6-N]_input Provides current temperature of each core.
