[PATCH 0/4] Fix S3 and S4 issues related to fbdev

[Mario Limonciello]

Moving to the generic fbdev helper introduced a regression in S4 support
on Hawaii PRO graphics cards.  A workaround commit was introduced to
avoid this S4 regression until the root cause could be found, but that
workaround commit introduced a completely separate regression on S3 on
a WX3200.

This series reverts all the code to move to generic fbdev helpers to
fix both issues.

Mario Limonciello (4):
  Revert "drm/amdgpu/display: disable prefer_shadow for generic fb
    helpers"
  Revert "drm/amdgpu: keep fbdev buffers pinned during suspend"
  Revert "drm/amdgpu: drop amdgpu_display_gem_fb_init()"
  Revert "drm/amdgpu: use generic fb helpers instead of setting up AMD
    own's."
