There are quite a few out of tree users that I know of that might be impacted. 
On the other hand, out of tree isn't an excuse, and OMAP3 platforms should 
move to DT. The good news is that DT support for the omap3isp driver is about 
to get submitted, and hopefully merged in v4.1. I thus have no objection to 
this patch.

Sakari, does it conflict with the omap3isp DT support ? If so, how would you 
prefer to resolve the conflict ? Russell, would it be fine to merge this 
through Mauro's tree ?
