[PATCH 2/3] of: Add Chunghwa Picture Tubes Ltd. vendor prefix

[Thierry Reding]

Chunghwa Picture Tubes Ltd. isn't listed on the stock exchange and just
Chunghwa is too generic, so use the official abbreviation "CPTT" as the
vendor prefix.

cptt is not very mnemonic. If plain "chungwa" is too generic (could you
expand upon that?), would "chungwapt" be better?

Well, there are Chunghwa Post and Chunghwa Telecom. I guess none of
these make devices that would ever need to be represented in a device
tree, but you never know.

I'm having some trouble understanding the criteria on how to choose a
good vendor prefix. As I mentioned in another subthread I remember some
discussion that concluded that the stock symbol should be used if one
existed. That's not the case for Chunghwa so I looked for some sort of
specific abbreviation. cptt is what Chunghwa Picture Tubes uses for
their website (http://www.cptt.com.tw) and seemed like a good fit. If
something mnemonic is preferred, perhaps we should just go with plain
"chunghwa". If it turns out that the newspaper or telecom company ever
do ship a product that needs a device tree representation we can always
come up with a variant then.

I don't think there are any hard/fast rules, which may be the problem!

I guess if I search Google for "cptt", the right website is the second
hit, so perhaps it's not so bad.

That'd probably be fine too. A telecom company at least seems like it
could easily start making HW, but like you say, we can deal with that
then!

As I suspect this is going to lead to confusion, and there don't seem to
be any bindings using this yet, I'd prefer "panasonic" as the vendor
prefix.

Thanks,

There was some discussion a few months back where it was recommended to
use the stock symbols for vendor prefixes where one existed. According
to this[0], the symbol for Panasonic Corporation is "PC".

My only concern here is that "pc" may get abused elsewhere in bindings
as a prefix, and may lead to general confusion due to other meanings for
"pc". As "panasonic" is clear to any reader without looking in
vendor-prefixes.txt, and there are no panasonic device bidnings using
"pc" as a prefix, I think that "panasonic" is preferable as a vendor
prefix.

Thanks,
Mark.

The changes since v2 mean that the commit messages now describe the
opposite of the patch.

Yes, I really didn't proof-read that commit message. I sent a v3 earlier
today that fixes this. Sorry for the noise.
