The smmu pm usage count underflow is concerning, the smmu pm should be tied to the GPU device via device_link_add(). I've never seen something similar, but I'm still on v6.14.

NP to revert but not so sure with only a sample set of two, I could say the change fixes. Anyway, I'll revert and if I see the bug again, we know its not that. --- bod
Add in a dtsi for the Dell Inspiron 14p. I'm currently using this as a daily driver including sending this series from. Its reasonably stable on 6.15-rcX. The first two patches can be applied without dependency, the final patch relies on patches staged for -next in the media tree to be applied, presently. https://gitlab.freedesktop.org/linux-media/media-committers/-/commit/2ab7f87a7f4bf392e3836a2600f115a1baa1415c https://lore.kernel.org/linux-media/20250407-b4-media-comitters-next-25-03-13-ov02e10-v4-0-211e3e6fae90@linaro.org/ Working for me included in this series: - USB Both Type-C USB ports Type-A port Fingerprint reader - WiFi - Bluetooth - RGB Camera - Toucpad, keyboard - Display Working for me but not included: - Audio jack - Iris Not working: - Speaker output Still WiP haven't touched this in a while - Battery Dell has its own Embedded Controller likely from the x86 platform reused on Qcom which we need to reverse engineer or get some information on to make faster progress on. - cDSP Haven't tried to bring this up. - EVA No driver haven't tried it. - Bugs Occasionally when resuming I get a fencing error with hyperlock and freedreno, TBH it looks like something in the GPU or SMMU according to Rob Clark: https://pastebin.com/AWjCyaap Ath12k has been splatting for me up to 6.14 when removing a SSID. I switched on ath12k debug when going to 6.15 and predictably couldn't reproduce the bug, either because the timings have changed as a result of Heisenbugging or because a fix has been slipped into ath12k. Other than those two I'm pretty happy with this system. The DTS is based on Aleksandrs Vinarskis XPS, Lenovo T14s and Qcom CRD.
