    53 This driver implements support for the Winbond W83781D, W83782D and W83783S. 
     57This driver implements support for the Winbond W83781D, W83782D, 
     58W8783S, and W83627HF chips. 
    5459We will refer to them collectively as W8378* chips.

    5661There is quite some difference between these chips, but they are similar 
    5762enough that it was sensible to put them together in one driver.  
     63The W83627HF chip is assumed to be identical to the W83782D.

    7278Overtemperature Shutdown limit is crossed; it is triggered again as soon as  
    73 it drops below the Hysteris value. A more useful behaviour  
    74 can be found by setting the Hysteris value to +127 degrees Celcius; in  
     79it drops below the Hysteresis value. A more useful behaviour  
     80can be found by setting the Hysteresis value to +127 degrees Celcius; in  
    7581this case, alarms are issued during all the time when the actual temperature 
    7682is above the Overtemperature Shutdown value. For the other sensor(s), an 
    7783alarm is triggered when the temperature gets higher then the Overtemperature  
    78 Shutdown value; it stays on until the temperature falls below the Hysteris  
     84Shutdown value; it stays on until the temperature falls below the Hysteresis
