Hi Alex,
I cherry-picked a bunch of fixes for 4.15. These can be found at
hwentlan/4.15-rc1-fixes.
Of the changes the highlighted ones (with *) in particular are highly
recommended, but even the other ones are probably good to have.

* fc59fdfdbd52 drm/amd/display: Switch to drm_atomic_helper_wait_for_flip_done
* c386a22129a1 drm/amd/display: fix gamma setting
* af54c36e0c30 drm/amd/display: Do not put drm_atomic_state on resume
89be3facaeb1 drm/amd/display: Fix couple more inconsistent NULL checks in
dc_resource

afmt.
b35eb4120a68 drm/amd/display: fix memory leaks on error exit return
ab164036ba33 drm/amd/display: check plane state before validating fbc
70d7f684a4d8 drm/amd/display: Do DC mode-change check when adding CRTCs
1baa90a34571 drm/amd/display: Revert noisy assert messages
7397a660300a drm/amd/display: fix split viewport rounding error
bd4eb434d515 drm/amd/display: Check aux channel before MST resume
65633318cedd drm/amd/display: fix split recout offset
9e403e8d7d07 drm/amd/display: Don't reject 3D timings
277a9b0854c4 drm/amd/display: Handle as MST first and then DP dongle if sink
support both
d5d60701f3ec drm/amd/display: fix split recout calculation
e947765cc008 drm/amd/display: Fix S3 topology change
405b3c636ac5 drm/amd/display: Add timing validation against dongle cap
* 1f63dba38d42 drm/amd/display: Should disable when new stream is null
fa4e15633102 drm/amd/display: Add null check for 24BPP (xfm and dpp)
I confirmed on Polaris11 the bolded changes fix:
* DPMS
* Gamma
The other fixes address a bunch of Raven stuff, as well as dock/dongle issues,
and potential problems found by smatch, but I haven't been able to confirm
those myself.
I gave S3 a spin since that is also problematic without "Do not put
drm_atomic_state on resume" but on my motherboard the system never comes out
of S3 on 4.15rc1, even without loading amdgpu and no X. This works on
amd-staging-drm-next, so must be a regression elsewhere in the kernel.
Can you pick these up for your fixes branch?
Harry
PS: I succesfully rebased all of amd-staging-dal-drm-next on 4.15-rc1 last
night. It was painless. Just had to skip these two patches:
drm/amdgpu Moving amdgpu asic types to a separate file
x86/PCI: Enable a 64bit BAR on AMD Family 15h (Models 30h-3fh)
Processors
