Subject: drm/i915/kbl: Use propper ddi buffer translation table for Kabylake ULT and ULX.
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=a5b7991c0a7b3ea33bc2848f6dc701f170e23b64;p=openwrt%2Fstaging%2Fblogic.git

drm/i915/kbl: Use propper ddi buffer translation table for Kabylake ULT and ULX.

Let's introduce ULT and ULX Kabylake definitions and start
using it for a propper DDI buffer translation.

v2: Remove extra white space. (Paulo)
