.Sh NAME
.Nm schsio
.Nd SMSC SCH311x LPC Super I/O
.Sh SYNOPSIS
.Cd "schsio* at isa? port 0x2e
.Cd "schsio* at isa? port 0x4e
.Cd "schsio* at isa? port 0x162e
.Cd "schsio* at isa? port 0x164e
.Sh DESCRIPTION
The
.Nm
driver provides support for the SMSC SCH3112, SCH3114, and SCH3116
ICs.
Among other things, the devices contain environment sensors, a watchdog
timer, and fan control.
The
.Nm
driver currently only supports the environment sensors.
The hardware provides the following sensors:
.Bl -column "Internal diode" "Units" "Typical" -offset indent
.It Sy "Sensor" Ta Sy "Units" Ta Sy "Typical use"
.It Li "Internal diode" Ta "uK" Ta "IC internal thermal diode"
.It Li "Remote diode 1" Ta "uK" Ta "External thermal diode"
.It Li "Remove diode 2" Ta "uK" Ta "External thermal diode"
.It Li "FAN1" Ta "RPM" Ta "Fan tachometer"
.It Li "FAN2" Ta "RPM" Ta "Fan tachometer"
.It Li "FAN3" Ta "RPM" Ta "Fan tachometer"
