[REGRESSION][BISECTED] wireless networking broken on Pinephone Pro

[Oren Klopfer]

Apologies if this is not formatted properly, this is my first submission to the kernel mailing list. WiFi specifications were introduced into the Pinephone Pro device tree in 096bd8c679185f898cae9933c6a68650fa26ea4f, but this causes complete networking failure on some devices. The regression affects all versions v6.18-rc1..v7.1-rc6.

An identical issue was reported for the Pinebook Pro at https://lore.kernel.org/all/aUKOlj-RvTYlrpiS@rock.grzadka/; the regression was reverted in 29d1f56c4f3001b7f547123e0a307c009ac717f8. The errors faced on the Pinephone Pro are exactly the same as were reported for the Pinebook Pro regression.

A previous patch at https://lore.kernel.org/all/20260112-ppp_connectivity-v1-3-284d6e83b212@gmail.com/ attempted to resolve this issue but never ended up being merged.

Reverting the commit allows wireless connection to function again. I am not really familiar with the process of submitting a revert patch, but I'd request that this be done on all of 6.18 (LTS), 7.0 (Stable), 7.1 (Mainline). Thanks!

Thx for the report. Sounds like a revert is the right course of action
here. Could you submit one with a stable tag to ensure backporting? That
might be the fastest way to resolve this, as that makes it easy to
process for the maintainers to process this.

Ciao, Thorsten

Was confused for like 5 minutes because "didn't we do that just recently",
until realizing, that it's the Pinephone this time, not the Pinebook.

So we'd need a similar one to
https://git.kernel.org/pub/scm/linux/kernel/git/soc/soc.git/commit/?h=for-next&id=29d1f56c4f3001b7f547123e0a307c009ac717f8
