The whole idea and requirements we agreed on initially was to implement 
it first for CHV/BSW and then implement it for BDW+. Hence the 
sequencing is like that.

I am afraid we are a bit late for this.
Matt has done 4 set of reviews in this order, and if I rearrange it, it 
would be too much to ask from him to do it all again.

If we consider this enabling all the features for one platform first and 
then extending it to others, this might not look that fragmented to you, 
try this out :)

I think I can split this into two patches.

Its pretty clear, actually, may be this would help.
On DRM layer its CTM, palette_befor_ctm and palette_after_ctm, which is 
as defined in the framework.
On i915 layer its CSC, degamma and gammma, which is specific to intel 
hardware. Does it make sense now ?
