This one, 
commit 4ac93fa0ec12a887b40b81d9b8b7fcd1033f48d5
drm/amd/display: add cyan_skillfish display support

Actually, it is fine before switching to amdgpu_discovery_set_ip_blocks.
During developing amdgpu_discovery_set_ip_blocks, it is not ready.
So skip to enable it.

I compiled amdgpu driver with this patch and loaded it on ubuntu 20.04. 
The display worked well. Otherwise the display won't work.

Lang
