X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=da411a48bdeb648153dc9a485c15c18f3d063eac;p=openwrt%2Fstaging%2Fblogic.git drm/i915/cfl: Basic DDI plumbing for Coffee Lake. All here is pretty much like Kabylake. Including CFL-U has to use same ddi translation table as KBL-U for now. v2: Include missed IS_COFFEELAKE on edp trans table. (DK) Handle CFL-U with same translation table as KBL-U. (DK and confirmed with HW engineers) v3: Adding missed case for IS_CFL_ULT. (DK). v4: Duh! Now with the real IS_CFL_ULT instead of KBL one. (DK) Also use IS_GEN9_BC when possible.
