Add dt-bindings for serial LIN bus adapters. These adapters are
basically just LIN transceivers that are hard-wired to serial devices.

Maybe I've just missed something on earlier versions that I didn't
read, but the name of the device on the website you link is "hexLIN",
so why is "lin-serdev" used here instead?

Hello Conor,

 thanks for having an eye on this, please see my answer below.

The USB one is called hexLIN and has it's own HID driver.

This serial LIN adapter doesn't really have a product name. Currently
on our website it's generically called 'UART LIN Adapter'.

This LIN adapter is basically just a LIN transceiver and very generic,
so that one could solder it to any single-board computer with an uart.

I think 'lin-serdev' for LIN and serial device fits great, also serdev
is the name of the used kernel infrastructure (besides the LIN glue
driver).

If you still don't like it, I'm open to other names. What about
"hexlin-uart" or "linser"?

Thanks

I dunno, I don't really care about it being called "hexlin,lin-serdev",
all that much, I just found it confusing that the link in the description
sent me to the ""Hello World" in LIN" section of your site. If it had
dropped me off at the "UART LIN adapter" section things woud've been less
confusing.

That said, calling the compatible after a linux-ism is a bit odd to me
when the device seems to be called a "UART LIN adapter" on the page, not
a "serdev".

Cheers,
Conor.

If there is no real, fixed model name, I would also propose to use
whatever is on the website currently and avoid Linuxism.

Hi Conor and Krzysztof,

I guess this is a chromium oddity, because browsing to

 https://hexdev.de/hexlin#hexLINSER

brings the user to another headline ("hexLIN" not "hexLINSER") as long
as headline "hexLINSER" can be also displayed.

When using firefox, the top headline is hexLINSER as expected (at least
I do).

OK, I changed it to hexLINSER on the website and in the upcoming v4
revision of this patchset. LINSER for LIN and serial, or like in
"Linsen & Spätzle" :)

Thanks

Yeah, I think its actually chrome that I saw it originally, but that's
probably irrelevant. After your re-org, in Chrome, if the window is small
enough, I still only see the "3 Open Source Tool: hexLIN" stuff, but
that's not an issue with the binding itself, so I won't hold things up
on that basis.
