Subject: [PATCH v2 0/5] drm/msm: support for host-cached BOs

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

v2:
 - added patches 2/3 to enable using dma_ops_bypass
 - changed DRM_MSM_GEM_SYNC_CACHE patch to use dma_sync_sg_for_device()
   and dma_sync_sg_for_cpu(), and renamed sync flags.

Not sure I did the right thing with for the dma_ops_bypass part,
this is what I came up with reading the emails.

Jonathan Marek (5):
  drm/msm: add MSM_BO_CACHED_COHERENT
  dma-direct: add dma_direct_bypass() to force direct ops
  drm/msm: call dma_direct_bypass()
  drm/msm: add DRM_MSM_GEM_SYNC_CACHE for non-coherent cache maintenance
  drm/msm: bump up the uapi version
