From: Paulo Zanoni Date: Thu, 22 Sep 2016 21:00:27 +0000 (-0300) Subject: drm/i915: SAGV is not SKL-only, so rename a few things X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=674f823b455cdb94d5773406c1caac170f87e1c4;p=linux-beck.git drm/i915: SAGV is not SKL-only, so rename a few things The plan is to introduce intel_has_sagv() and then use it to discover which platforms actually support it. I thought about keeping the functions with their current skl names, but found two problems: (i) skl_has_sagv() would become a very confusing name, and (ii) intel_atomic_commit_tail() doesn't seem to be calling any functions whose name start with a platform name, so the "intel_" naming scheme seems make more sense than the "firstplatorm_" naming scheme here.
