Hi Pavel,

What I've done is just rebased the ccp2 branch. In other words, the patches
in that branch are no more ready than they were.

To get these merged we should ideally

1) Make sure there will be no regressions,

2) clean things up in the omap3isp; which resources are needed and when
(e.g. regulators, PHY configuration) isn't clear at the moment and

2) have one driver using the implementation.

At least 1) is needed. I think a number of framework patches could be
mergeable before 2) and 3) are done. I can prepare a set later this week.
But even that'd be likely for 4.14, not 4.13.
