As requested in V1, we separated out the iris driver code in functional
patches. Also, as commented in 1st patch, we are OK to have the common
helpers as separate series.

Patch 6 onward all the code is contained to iris driver only.
Could you please elaborate, what do you mean by squashing down the changes?
which patches you want us to squash?
