Sounds good.

I'm basing it on the PCI id I see in dmesg, which is 1002:15d8, which
the driver looks to identify as CHIP_RAVEN and flag with
AMD_APU_IS_PICASSO. Based on that it will pick firmware files which
begin with "picasso".  It would be informative though to have the output
from "lspci -vvnn" on your machine.

Let's try the picasso files first. If that doesn't work you can try the
vega10 files (without the new picasso files), then if that doesn't work,
try both. Then we'll have an idea about what the minimal set of files is
to fix the problem.
