While I guess valid, the tools (b4) don't like the '/' in your
message-id. Lore will escape it fine, but then you have to escape the
url. Would be nice to avoid all that, but maybe this is Exchange's
doing?

Expand what each region is:

reg:
items:
- description: ...
- description: ...
- description: ...

And then drop this.

It should be compatible with altera's socfpga family.
Should i leave a general compatible field such as "altr,msgdma" ?

example:
compatible:
enum:
- altr,socfpga-msgdma
- altr,msgdma

in broken and the 2/2 patch doesnt appear along with this in thread, pls
