Add scc(4), a driver for serial communications controllers. These

controllers typically have multiple channels and support a number
of serial communications protocols. The scc(4) driver is itself
an umbrella driver that delegates the control over each channel
and mode to a subordinate driver (like uart(4)).
The scc(4) driver supports the Siemens SAB 82532 and the Zilog
Z8530 and replaces puc(4) for these devices.

+.Sh SYNOPSIS
+.Cd "device scc"
+.Cd "device uart"
+.\"
+.Sh DESCRIPTION
+The
+.Nm
+device driver provides support for various classes of SCCs.
+It is an umbrella driver that delegates control of each independent
+communication channel to subordinate drivers.
+These subordinate drivers, like
+.Xr uart 4 ,
+take care of the details of the communication itself.
+.\"
+.Sh HARDWARE
+The
+.Nm
+driver supports the following classes of SCCs:
+.Pp
+.Bl -bullet -compact
+.It
+SAB82532: Siemens SAB 82532 based serial communications controllers.
+.It
+Z8530: Zilog 8530 based serial communications controllers.
