I do see many dts named in the format you described here and I agree it is very clear. But at Broadcom we use a slight different format for reference boards that we started from day 1: bcm9<soc>-<ref board model>.dts such as bcm963138REF.dts. And there are many in the kernel as well if you search "bcm9*.dts". Many of them are Broadcom reference boards and some are actual consumer product.On 2022-07-21 02:07, William Zhang wrote:Add generic bcm94908.dts file.

I think I see some inconsistency in naming Broadcom's reference boards DTS files. If you take a look at in-kernel DTS files: find ./arch/arm*/boot/dts/ -name "*.dts" 99% of them are prefixed with family/SoC name. I did the same for bcm4908 (and Northstar) boards. So it's <soc>-<manufacturer>-<model>.dts e.g. bcm4908-asus-gt-ac5300.dts To match that I *think* you should actually call your file: bcm4908-bcm94908 (or bcm4908-94908 depending on actual board name) First of all: am I correct here?
I actually was thinking to ask you if we can change all the 4908 boards to use bcm94908- prefix to be consistent with Broadcom board name convention. But at the second thought, I didn't ask because it does not make much benefit other than a uniform name, unless you agree and I can make that change. Otherwise, I would rather keep them as they are now because we have ton of reference boards here and we don't want to make that changes to remove the 9 (which will definitive cause big confusing internally) and there are no rule in linux for the name as far as I know. What I can do is update the bcmbca.yaml to put bcmbca board name rule bcm9<soc>-<ref board model>.dts for broadcom reference board and bcm<soc>-<manufacturer>-<model>.dts for customer board, if that sounds good to you.Secondly: could you do that? I know many DTS files named ignoring SoC/ family prefix. Still maybe we could change it as some (this) point?
