Note, I also submitted a patch to add support for the AVR-DA and AVR-DB families here:
https://gcc.gnu.org/pipermail/gcc-patches/2022-April/592668.html

No response so far.

Are these independent of patch from Joel Holdworth?  I think so, but I'm 
not at all familiar with the avr family of chips, so it'd be good if 
someone with more familiarity would chime in.

I think you need to update avr-mmcu.texi for the new chips as well.
