NAME
     itesio — ITE IT87xxF Super I/O driver

SYNOPSIS

DESCRIPTION
     The itesio driver provides support for the Environment Controller and the
     Watchdog Timer on the IT87xxF Super I/Os, and may be used to monitor
     hardware sensors or setting up a watchdog timeout value for the system.

     The itesio driver has 15 sensors:

	   VIN3	     uV DC    +5V
	   VIN4	     uV DC    +12V
	   VIN5	     uV DC    -12V
	   VIN6	     uV DC    -5V
	   VIN7	     uV DC    STANDBY
	   VBAT	     uV DC    VBAT

     The itesio Watchdog Timer is configurable via the wdogctl(8) utility and
     has a resolution between 1 and 65535 seconds.  The Watchdog Timer is not
     supported on the IT8705 Super I/O.
