There are quite a few reports off-list that, at least on Hamoa based devices, there are some IOMMU faults and some abnormal artifacts on eDP. These have been traced to the quad pipe support introduced in 6.19-rc1.
Meanwhile, Marijn reported some issues in some dual-DSI dual-DSC scenario. Off-list discussion concluded into reverting these two commits to avoid the described issues.
