Subject: [PATCH 0/3] drm/msm: support for host-cached BOs

This is to support cached and cached-coherent memory types in vulkan.

I made a corresponding WIP merge request [1] which shows usage of this.

Jonathan Marek (3):
  drm/msm: add MSM_BO_CACHED_COHERENT
  drm/msm: add DRM_MSM_GEM_SYNC_CACHE for non-coherent cache maintenance
  drm/msm: bump up the uapi version
