[PATCH 0/3] Enable Scatter Gather for Picasso.

[Andrey Grodzovsky]

This series enables S/G for Picasso.
First 2 patches fix a hard hang introduced by placing the display
BO in GTT memory because of HW issues with cached mappings
and the third patch enables S/G.

Andrey Grodzovsky (2):
  drm/amdgpu: Fix hard hang for S/G display BOs.
  drm/amd/display: Only allow s/g when USWC flag is set.

Shirish S (1):
  drm/amd: enable S/G for RAVEN chip
