I was building against amd-staging-drm-next (commit e4a67e6cf14c).
v4 will contain just the drm-mst patches and will apply on latest drm-tip/drm-tip (commit 018886de4726)

Subject: Re: [PATCH v3 00/16] Display Stream Compression (DSC) for AMD Navi
What branch does this patch series actually apply to? I've been trying to
apply this locally, but it doesn't appear to apply against drm-tip/drm-tip,
amdgpu-next/drm-next, or origin (e.g. kernel.org) /master. Is there any chance
we could have this go against drm-tip instead (and even better, split out the
DRM-specific bits into their own patch series?)
