Sorry, I missed that you had cc'd the list - just noticed it in the
next patch and thought that was odd!

Anyhow, good work - we'll just wait for them to have a chance to look
at it :)

Hi Eugen,

CC the device tree maintainers and list for devicetree binding changes.

I've added them.   This one is unusual enough it will need and Ack from
that direction (and I prefer to get them even for the trivial patches
when Rob and Mark aren't too busy!)
