Subject: [PATCH 0/3] drm/etnaviv: IOMMU related fixes

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.

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
