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

Expand what each region is:
reg:
items:
- 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
Thanks,
Olivier

These should be two separate patches... Also threading in your patches
in broken and the 2/2 patch doesnt appear along with this in thread, pls
fix that as well
