tty: cyclades, remove this orphan
Browse files Browse the repository at this point in the history 
The Cyclades driver was orphaned by commit d459883 (MAINTAINERS:
remove two dead e-mail) 13 years ago. Noone stepped up to take care of
them and to fix all the issues the driver has.

On the top of that, there is no way to obtain the firmware for Z cards
from the vendor as cyclades.com ceased to exist.

So it's time to drop the driver with all its traces.

config CYCLADES
tristate "Cyclades async mux support"

help
This driver supports Cyclades Z and Y multiserial boards.
You would need something like this to connect more than two modems to
your Linux box, for instance in order to become a dial-in server.

For information about the Cyclades-Z card, read
<file:Documentation/driver-api/serial/cyclades_z.rst>.

To compile this driver as a module, choose M here: the
module will be called cyclades.

If you haven't heard about it, it's safe to say N.

config CYZ_INTR
bool "Cyclades-Z interrupt mode operation"
depends on CYCLADES && PCI
help
The Cyclades-Z family of multiport cards allows 2 (two) driver op
modes: polling and interrupt. In polling mode, the driver will check
the status of the Cyclades-Z ports every certain amount of time
(which is called polling cycle and is configurable). In interrupt
mode, it will use an interrupt line (IRQ) in order to check the
status of the Cyclades-Z ports. The default op mode is polling. If
unsure, say N.
