The property is needed in order to trigger VL805's firmware load. Note
that there is a gap between the property introduced and the previous
one. This is also the case downstream.

I don't know what "downstream" means, so I don't know what we're
syncing *with*.  If there's another branch or project we need to
coordinate with, is there a name or URL that would help facilitate
that?  If not, I'm not sure what value that sentence adds.

Downstream here means the Raspberry Pi maintained kernel whose tree can
be found here:

https://github.com/raspberrypi/linux/

Changes appear there first, and people like Nicolas and Stefan try to
get them upstream from that tree into Linus' tree.
