+
+This driver supports hardware monitoring for Analog Devices LTC2991 Octal I2C
+Voltage, Current and Temperature Monitor.
+
+The LTC2991 is used to monitor system temperatures, voltages and currents.
+Through the I2C serial interface, the eight monitors can individually measure
+supply voltages and can be paired for differential measurements of current sense
+resistors or temperature sensing transistors. Additional measurements include
+internal temperatureand internal VCC.

+Description
+-----------
+
+This driver implements support for the ChargerLAB POWER-Z USB-C power testing
+family.
+
+The device communicates with the custom protocol over USB.
+
+The channel labels exposed via hwmon match the labels used by the on-device
+display and the official POWER-Z PC software.
+
+As current can flow in both directions through the tester the sign of the
+channel "curr1_input" (label "IBUS") indicates the direction.

+Controlling fan speed
+---------------------
+
+The SCH5627 allows for partially controlling the fan speed. If a temperature
+channel excedes tempX_max, all fans are forced to maximum speed. The same is not
+true for tempX_crit, presumably some other measures to cool down the system are
+take in this case.
+In which way the value of fanX_min affects the fan speed is currently unknown.
