Tested-by: Val Packett # sc7180-ecs-liva-qc710 Might be worth noting in the commit message that the real world issue this solves is that after probing the driver, the DPU would keep trying to access the physical address that belonged to the EFI framebuffer, causing constant IOMMU faults and visual glitches on the display output. ~val P.S. what a coincidence that just a week ago this was discussed for sdm845 https://lore.kernel.org/all/bfe55d1b-1b45-4187-84fe-9475cb90b00a@linaro.org/
