Hi Conor,
Sorry, I missed the news of you becoming a DT maintainer, so most of my
previous points are obviously bogus. And congrats :)
I've been doing it for over a year, so news travels to some corners slowly
I guess. I'm not just being a pest in dozens of subsystems for fun!

The WL-355608-A8 is a 3.5" 640x480@60Hz RGB LCD display used in a
number of handheld gaming devices made by Anbernic. By consensus a
vendor prefix is not provided as the panel OEM is unknown.
Where has this consensus been found?
I had a look at the previous discussions, and I can't find any consensus
being reached there. And for that kind of thing, having the ack or
review of any of the DT maintainers would have been great.
There was a consensus with Conor, this is why he acked v2, see
https://lore.kernel.org/all/20240525-velvet-citable-a45dd06847a7@spud/
It's probably a matter of semantics here, but if it's with only one
person, it's not a consensus but an agreement.
```
I think if we genuinely do not know what the vendor is then we just
don't have a prefix.
```
And even then, I don't interpret Conor's statement as a formal agreement
but rather an acknowledgment of the issue.
I mean, I specifically left an r-b below that line in v2:

I'm not a displays guy, so my sources were limited to what I could find
from search engines, but I spent some time looking for an actual vendor
of the panel and could not. All I found was various listings on places
like AliExpress that did not mention an manufacturer. I'd rather not
invent a vendor because we could not find the actual vendor of the
panel & it seemed rather unreasonable to block support for the device
on the basis of not being able to figure out the vendor. If you, as
someone knowledgeable on displays, can figure the vendor out, then
yeah we should definitely add it.
It's still a bit surprising to me. We've merged[1][2][3][4], and are still
merging[5], panels from this particular vendor that have no clearly
identified OEMs. Just like any other panel, really. We almost *never*
have the actual OEM, we just go with whatever is the easiest to identify
it.
It wasn't (isn't?) clear to me that Abernic is even the vendor of the
panel, just that it works for their devices. If there's an established
policy here of making up vendors for these panels, then sure, override
me and use them as the prefix.
Plus, if there ever is another WL-355608-A8 part from a completely
unrelated vendor, then you'll have a naming clash with no clear
indication about which is which.
Not sure we can say there's an established policy ongoing here, we try to
use the marking we find on the panel when possible and when not possible
we use the vendor + name of the device in last ressort.
