    pccard: Remove cmx(4) driver
    
    The only attachment of cmx was pccard, so remove the driver in
    anticipation of PC Card support removal.

-.Sh NAME
-.Nm cmx
-.Nd Omnikey CardMan 4040 smartcard reader device driver
-.Sh SYNOPSIS
-.Cd device cmx
-.Sh DEPRECATION NOTICE
-This driver is scheduled for removal prior to the release of
-.Fx 13.0
-.Sh DESCRIPTION
-The
-.Nm
-driver provides support for the PCCARD based
-.Em Omnikey CardMan 4040
-smartcard reader.
-The driver provides a character device special file based
-.Em Chip/Smart Card Interface Devices (CCID)
-interface.
-The driver implements what the vendor calls the
-.Em Synchronous API
-onto the smartcard reader device.
-.Pp
-Reading and writing is synchronous, meaning that a call to
-.Xr write 2
-directly corresponds to a complete CCID command sent to the
-device, while the following
-.Xr read 2
-will return the complete answer from the reader.
-There is no support for partial reads or writes.
-There is no upper limit on
-CCID request or response sizes, but the complete CCID request
-must be sent to the driver in
-.Xr write 2
-and the complete CCID response must fit into the buffer
-supplied to
-.Xr read 2 .
-.Pp
-Non-blocking I/O,
-.Xr select 2
-and
-.Xr poll 2
-are supported and work as expected.
-An open file descriptor
-will always be ready for writing, but only ready for reading
-if the device indicates that it has data available.
-.Sh FILES
-.Bl -tag -width /usr/ports/security/openct -compact
-.It Pa /dev/cmx\fBn\fP
-Character device special file.
-.It Pa /usr/ports/security/openct
-OpenCT, a userspace smartcard daemon containing a
-.Em CCID
-driver which directly supports
-.Nm
-devices.
-.\".It Pa /usr/ports/devel/pcsc-lite
-.\"PC/SC-Lite, a userspace smartcard daemon.
-.\".It Pa /usr/ports/devel/libccid
-.\"libccid, a generic
-.\".Em CCID
-.\"driver for use by PC/SC-Lite to interface to
-.\".Nm
-.\"devices.
-.El
-.Sh COMPATIBILITY
-Userland smartcard code written for the vendor's Linux drivers
-should work with the
-.Nm
-driver without modification.
-.Sh SEE ALSO
-.Xr pccard 4
-.Sh HISTORY
-The
-.Nm cmx
-driver first appeared in
-.Fx 7.1 .
-.Sh AUTHORS
-.An -nosplit
-The
-.Nm
-driver was written by
-.An Daniel Roethlisberger Aq Mt daniel at roe.ch ,
-originally based on the Linux driver v1.1.0 by
-.An Omnikey GmbH Lk www.omnikey.com .
-Early testing and bug fixes by
-.An Marcin Cieslak Aq Mt saper at system.pl .
-.Sh BUGS
-.An -nosplit
-The way the
-.Nm
-driver talks to the CardMan 4040 is a bit rough.
-Due to the complete lack of hardware documentation other than vendor drivers
-for other operating systems, the gory details of the device's
-I/O registers are not understood very well.
-There may be error conditions which can only be solved by physically
-reinserting the reader.
