[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!
