From 855c79f5212acced123c1a6be3c12601f45e8da9 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Thu, 2 Mar 2017 19:14:54 +0200 Subject: [PATCH] drm/i915: Plop vlv wm state into crtc_state MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Relocate the vlv/chv wm state to live under intel_crtc_state. Note that for now this just behaves as a temporary storage. But it'll be easier to conver the thing over to properly pre-computing the state when it's already in the right place.
