-Description
------------
-
-This driver implements support for the Texas Instruments ADC128D818.
-It is described as 'ADC System Monitor with Temperature Sensor'.
-
-The ADC128D818 implements one temperature sensor and seven voltage sensors.
-
-Temperatures are measured in degrees Celsius. There is one set of limits.
-When the HOT Temperature Limit is crossed, this will cause an alarm that will
-be reasserted until the temperature drops below the HOT Hysteresis.
-Measurements are guaranteed between -55 and +125 degrees. The temperature
-measurement has a resolution of 0.5 degrees; the limits have a resolution
-of 1 degree.
-
-Voltage sensors (also known as IN sensors) report their values in volts.
-An alarm is triggered if the voltage has crossed a programmable minimum
-or maximum limit. Note that minimum in this case always means 'closest to
-zero'; this is important for negative voltage measurements. All voltage
-inputs can measure voltages between 0 and 2.55 volts, with a resolution
-of 0.625 mV.
-
-If an alarm triggers, it will remain triggered until the hardware register
-is read at least once. This means that the cause for the alarm may
-already have disappeared by the time the alarm is read. The driver
-caches the alarm status for each sensor until it is at least reported
-once, to ensure that alarms are reported to user space.
-
-The ADC128D818 only updates its values approximately once per second;
-reading it more often will do no harm, but will return 'old' values.
-
-In addition to the scanned address list, the chip can also be configured for
-addresses 0x35 to 0x37. Those addresses are not scanned. You have to instantiate
-the driver explicitly if the chip is configured for any of those addresses in
-your system.
