Marcel Moolenaar 6174e6ed12 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 NAME
.Nm scc
.Nd driver for Serial Communications Controllers (SCC) 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.

.Sh HISTORY
The
.Nm
device driver first appeared in
.Fx 7.0 .
.Sh AUTHORS
