+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.

+temp[N]_label		Provides string "DIMM CI", where C is DIMM channel and

+temp[N]_input		Provides current temperature of the populated DIMM.
+temp[N]_max		Provides thermal control temperature of the DIMM.
+temp[N]_crit		Provides shutdown temperature of the DIMM.

+
+Note:
+	DIMM temperature attributes will appear when the client CPU's BIOS
