+Description
+-----------
+
+From the datasheet:
+
+"The EMC6W201 is an environmental monitoring device with automatic fan
+control capability and enhanced system acoustics for noise suppression.
+This ACPI compliant device provides hardware monitoring for up to six
+voltages (including its own VCC) and five external thermal sensors,
+measures the speed of up to five fans, and controls the speed of
+multiple DC fans using three Pulse Width Modulator (PWM) outputs. Note
+that it is possible to control more than three fans by connecting two
+fans to one PWM output. The EMC6W201 will be available in a 36-pin
+QFN package."
+
+The device is functionally close to the EMC6D100 series, but is
+register-incompatible.
+
+The driver currently only supports the monitoring of the voltages,
+temperatures and fan speeds. Limits can be changed. Alarms are not
+supported, and neither is fan speed control.
+
+
+Known Systems With EMC6W201
+---------------------------
+
+The EMC6W201 is a rare device, only found on a few systems, made in
+2005 and 2006. Known systems with this device:
+* Dell Precision 670 workstation
+* Gigabyte 2CEWH mainboard

+Description
+-----------
+
+This driver permits reading of registers providing power information
+of AMD Family 15h processors.
+
+For AMD Family 15h processors the following power values can be
+calculated using different processor northbridge function registers:
+
+* BasePwrWatts: Specifies in watts the maximum amount of power
+  consumed by the processor for NB and logic external to the core.
+* ProcessorPwrWatts: Specifies in watts the maximum amount of power
+  the processor can support.
+* CurrPwrWatts: Specifies in watts the current amount of power being
+  consumed by the processor.
+
+This driver provides ProcessorPwrWatts and CurrPwrWatts:
+* power1_crit (ProcessorPwrWatts)
+* power1_input (CurrPwrWatts)
+
+On multi-node processors the calculated value is for the entire
+package and not for a single node. Thus the driver creates sysfs
+attributes only for internal node0 of a multi-node processor.
