[PATCH v4 0/7] Camera synchronisation

[David Plowman]

Hi everyone

Here's an updated set of camera sync patches. The only changes are the
tags that Kieran and Naush added, plus a handful of very minor
cosmetic things.

I'm hoping we can make some progress towards getting at least some of
this merged (the first patch in particular looks to have plenty of
tags already!), plus further reviews where these are still required.

Thanks!
David
