+.Sh NAME
+.Nm config_attach, config_detach, config_detach_children
+.Nd attach and detach devices
+.Sh SYNOPSIS
+.In sys/param.h
+.In sys/device.h
+.Ft "struct device *"
+.Fn config_attach "struct device *parent" "void *cf" "void *aux" \
+                  "cfprint_t print"
+.Ft "int"
+.Fn config_detach "struct device *dev" "int flags"
+.Ft "int"
+.Fn config_detach_children "struct device *parent" "int flags"
+.Sh DESCRIPTION
+.Pp
+The
+.Fn config_attach
+function attaches a found device.
+Memory is allocated for the
+.Em softc
+structure and the driver's attach function is called according to the
+configuration table.
+If successful,
+.Fn config_attach
+returns the
+.Em softc .
+If unsuccessful, it returns
+.Dv NULL .
+.Pp
+The
+.Fn config_detach
+function is called by the parent to detach the child device.
+The second argument
+.Fa flags
+contains detachment flags:
+.Bd -literal
+#define	DETACH_FORCE	0x01	/* Force detachment; hardware gone */
+#define	DETACH_QUIET	0x02	/* Don't print a notice */
+.Ed
+.Sh CONTEXT
+.Fn config_detach
+is always called from process context, allowing
+.Xr tsleep 9
+to be called while the device detaches itself (to deal with processes
+which have a device open).
+.Sh RETURN VALUES
+.Fn config_detach
+returns zero if successful and an error code otherwise.
+.Sh SEE ALSO
