AMD has added support for the "Sienna Cichlid" GPU to a new driver file for Linux. VideoCardz offers some background info and speculates that this is Navi21, the upcoming "Big Navi" GPU.
According to Phoronix, the new patches confirm this is Navi-based GPU with VCN 3.0 capabilities for video encoding and DCN3 update on the display front.

More importantly, however, this update will not make it to the Linux 5.9 kernel merge window in August, meaning the Sienna Cichlid is likely to launch after the month of August.
AMD’s Alex Deucher offers the following statement:
Sienna Cichlid is a GPU from AMD. This patch set adds support for it including power management, display, kfd, interrupts, gfx, multi-media, etc. The new register headers are really big so I haven’t sent them to the list. You can view the new patches including the register headers on the following git branch […]
In case you're wondering, cichlids are a species of fish.
