In this case, kernel is unable to map simple drm device and fail to boot (Note that for "DMA_API" it works fine). See, drivers/iommu/arm/arm-smmu/arm-smmu.c:arm_smmu_device_dt_probe() for more information. I have seen the error for the following arm64 instances in testflinger: moigno, igor, egede. Updating the firmware seems like one of the possible solutions. I have seen this error in 6.8 kernels (noble+jammy). However, both series should fail regardless of the kernel version. Focal can be different since "CONFIG_ARM_SMMU_LEGACY_DT_BINDINGS" config options is not defined there. If Focal works, we can remove this config option from Jammy and Noble. See error messages below for more information.
