Resolver of original Ryzen 2 temperature support:

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=218264

"In Progress" issue for Ryzen 5 support with patch:

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=239607

Was committed to head (CURRENT), apparently merged to stable/12 (cant 
find the MFC commit).

I've updated/retriaged the issue, and asked about a merge to stable/11, 
but at this point it looks like it missed the 12.1-RELEASE window
