Thanks for the patches. I am working on the DSC support on i915 for eDP/DP
as well. Looking at the patches below, this is specific to VDSC enabling for eDP
panels and not for the external DP.
So please mention that specifically in the cover letter as well.

Please specify that this enables VDSC for eDp in i915 gfx driver.

I do have a DSC eDP panel here in Oregon and can volunteer for testing your 
patches with that on GLK RVP.
