From c7ae7e9ab2078ed987903bc6c308abe57d575a59 Mon Sep 17 00:00:00 2001 From: Rodrigo Vivi Date: Tue, 6 Jun 2017 13:30:36 -0700 Subject: [PATCH] drm/i915/cnl: Configure EU slice power gating. Cannonlake also supports slice power gating on devices with more than one slice as SKL. Let's assume that this is the same for SKL+ and exclude BXT only. v2: Also remove KBL.
