2021-11-26tty: move tty_ldisc docs to new Documentation/tty/Jiri Slaby
Create a new directory in Documentation/ called tty. We will create more documents in it in the next patches, so let's have this one in the very same place. Change title accordingly and all the headers. This is the way what other documents look like in this directory in the next patches. So make this unified. And add a TOC.

2021-11-26tty: reformat tty_struct::flags into kernel-docJiri Slaby
Move the partial tty_struct::flags documentation from tty_ldisc to the tty.h header and combine it with the one-liners present there. Convert all those to kernel-doc. This way, we can simply reference the documentation in Documentation while the text is still along the definitions.

2021-11-26tty: combine tty_ldisc_ops docs into kernel-docJiri Slaby

2021-09-22tty: make tty_ldisc_ops::hangup return voidJiri Slaby
The documentation says that the return value of tty_ldisc_ops::hangup hook is ignored. And it really is, so there is no point for its return type to be int. Switch it to void and all the hooks too.

2021-06-18mxser: drop ISA supportJiri Slaby
While mxser PCI cards are still around and produced (Moxa provided me with two recently), ISA cards are obsolete for a long time. I haven't seen anyone using the cards and the ISA code paths are barely tested. Hence, remove ISA support from mxser driver so that we can clean the driver up.

2021-03-10tty: rocket, remove the driverJiri Slaby
While the driver is still marked as maintained in MAINTAINERS, Comtrol does not really care about this ancient driver. They are still manufacturing serial devices, but those are controlled only by out-of-tree drivers. Comtrol didn't answer my pings, so this driver is apparently unmaintained. Aside from that, the driver was untouched for years, only whole-tree changes happened during the past years. The driver needs much more care, so drop it for now. If someone steps up to reintroduce it, they need to clean it up first.

2021-03-10tty: cyclades, remove this orphanJiri Slaby
The Cyclades driver was orphaned by commit d459883e6c54 (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.

2020-07-21tty: vt: Replace HTTP links with HTTPS onesAlexander A. Klimov
Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.
