Right, so looking back in the git history, this project has been going
on for... at least four years?  Probably longer than the length of time
that we've been converting ARM to DT.  At no point during that has anyone
brought up the issue of DT being dynamic, so none of the drivers which
we have been converting caters for this.

Isn't this a bit of a missed opportunity, if this is a direction that
OF wishes to head towards?

Wouldn't it have been relevant to the discussion at kernel summit too,
concerning DRM/v4l2/componentised systems?  What if someone comes along
tomorrow with part of their multimedia based system inside a FPGA
which they program up at runtime?

FTTC broadband for 0.8mile line: now at 9.7Mbps down 460kbps up... slowly
improving, and getting towards what was expected from it.
