This patch series fixes usage of the etnaviv driver with GPUs behind a
IOMMU. It was tested on a NXP LS1028A SoC. Together with Lucas' MMU patches
[1] there are not more (GPU internal) MMU nor (system) IOMMU faults on the
LS1028A.

[1] https://lists.freedesktop.org/archives/etnaviv/2021-August/003682.html

changes since v1:
- don't move the former dma_mask setup code around in patch 2/3. Will
avoid any confusion.

Michael Walle (3):
drm/etnaviv: use PLATFORM_DEVID_NONE
drm/etnaviv: fix dma configuration of the virtual device
drm/etnaviv: use a 32 bit mask as coherent DMA mask
