[v2,0/3] Initial Panfrost driver

Message

Rob Herring (Arm) April 1, 2019, 7:47 a.m. UTC

Here's v2 of the panfrost driver. Lots of improvements from the RFC
primarily with support for job hangs resetting the GPU and runtime-pm
thanks to Tomeu.

Several dependencies have been applied already, but the first 2 patches
are the remaining dependencies. We need to take the iommu change via
drm-misc or we need a stable branch.

A git branch is here[1].

  iommu: io-pgtable: Add ARM Mali midgard MMU page table format
  drm: Add a drm_gem_objects_lookup helper
  drm/panfrost: Add initial panfrost driver
