Merge tag 'drm-next-2025-12-03' of https://gitlab.freedesktop.org/drm/kernel
Pull drm updates from Dave Airlie:
"There was a rather late merge of a new color pipeline feature, that
some userspace projects are blocked on, and has seen a lot of work in
amdgpu. This should have seen some time in -next. There is additional
support for this for Intel, that if it arrives in the next day or two
I'll pass it on in another pull request and you can decide if you want
to take it.
Highlights:
- Arm Ethos NPU accelerator driver
- new DRM color pipeline support
- amdgpu will now run discrete SI/CIK cards instead of radeon, which
enables vulkan support in userspace
- msm gets gen8 gpu support
