The DMA configuration of the virtual device is inherited from the first
actual etnaviv device. Unfortunately, this doesn't work with an IOMMU:
[ 5.191008] Failed to set up IOMMU for device (null); retaining platform DMA ops
This is because there is no associated iommu_group with the device. The
group is set in iommu_group_add_device() which is eventually called by
device_add() via the platform bus:
device_add()
blocking_notifier_call_chain()
iommu_bus_notifier()
iommu_probe_device()
__iommu_probe_device()
iommu_group_get_for_dev()
iommu_group_add_device()
Move of_dma_configure() into the probe function, which is called after
device_add(). Normally, the platform code will already call it itself
if .of_node is set. Unfortunately, this isn't the case here.
