 This hardware includes single main counter with known increment frequency
-(10MHz or more), and several programable comparators (optionally with

 automatic reload feature).
 When value of the main counter matches current value of any comparator,
 interrupt can be generated.
 Depending on hardware capabilities and configuration, interrupt can be
 delivered as regular I/O APIC interrupt (ISA or PCI) in range from 0 to 31,
 or as Front Side Bus interrupt, alike to PCI MSI interrupts, or in so called

+"LegacyReplacement Route" HPET can steal IRQ0 of i8254 and IRQ8 of the RTC.
 Interrupt can be either edge- or level-triggered. In last case they could be
 safely shared with PCI IRQs.
 Driver prefers to use FSB interrupts, if supported, to avoid sharing.

+.Sh NAME
+.Nm glxiic
+.Nd Geode LX CS5536 I2C controller driver
+.Sh SYNOPSIS
+To compile this driver into the kernel,
+place the following lines in your
+kernel configuration file:
+.Bd -ragged -offset indent
+.Cd "device pci"
+.Cd "device isa"
+.Cd "device glxiic"
+.Cd "device iicbus"
+.Ed
+.Pp
+Alternatively, to load the driver as a
+module at boot time, place the following line in
+.Xr loader.conf 5 :
+.Bd -literal -offset indent
+glxiic_load="YES"
+.Ed
+.Sh DESCRIPTION
+The
+.Nm
+driver supports the System Management Bus controller of the Geode LX
+series CS5536 Companion Device.  The Geode LX is a member of the AMD
+Geode family of integrated x86 system chips.
+.Pp
+Although AMD refers to this device as a System Management Bus (SMBus)
+controller, it is really an I2C controller (it lacks SMBus ALERT# and
+Alert Response support).
+.Pp
+The
+.Nm
+driver supports both I2C master and slave mode.
+.Sh SYSCTL VARIABLE
+The
+.Nm
+driver supports the following variable as both
+.Xr sysctl 8
+and
+.Xr loader 8
+tunable:
+.Bl -tag -width indent
+.It Va dev.glxiic.0.timeout
+This variable controls the I2C bus timeout in milliseconds.  The
+default timeout is 35 milliseconds.  A value of zero disables the
+timeout.
+.El
+.Sh CAVEAT
+The
+.Nm
+driver uses the interrupt line number configured by the board firmware
+by default.  If no interrupt line number has been configured by the
+board firmware (or to override the interrupt line number configured by
+board firmware), place the following line in
+.Xr device.hints 5 :
+.Bd -ragged -offset indent
+hint.glxiic.0.irq="10"
+.Ed
+.Pp
+The interrupt line number must be between 1 and 15.
