drm/amdgpu: adjust default display clock

Increase the default display clock on newer asics to
accomodate some high res modes with really high refresh
rates.

drm/amdgpu: Fix overflow of watermark calcs at > 4k resolutions.

2017-06-14T13:25:05+00:00

Commit d63c277dc672e0
("drm/amdgpu: Make display watermark calculations more accurate")
made watermark calculations more accurate, but not for > 4k
resolutions on 32-Bit architectures, as it introduced an integer
overflow for those setups and resolutions.

Fix this by proper u64 casting and division.

Merge tag 'gcc-plugins-v4.12-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux

2017-06-01T23:17:42+00:00

Pull gcc-plugin prepwork from Kees Cook:
 "Use designated initializers for mtk-vcodec, powerplay, amdgpu, and
  sgi-xp. Use ERR_CAST() to avoid cross-structure cast in ocf2, ntfs,
  and NFS.

  Christoph Hellwig recommended that I send these fixes now, rather than
  waiting for the v4.13 merge window. These are all initializer and cast
  fixes needed for the future randstruct plugin that haven't been picked
  up by the respective maintainers"

drm/amdgpu: Program ring for vce instance 1 at its register space

2017-05-31T17:09:15+00:00

We need program ring buffer on instance 1 register space domain,
when only if instance 1 available, with two instances or instance 0,
and we need only program instance 0 regsiter space domain for ring.
