From 07464c7c0cf773b86372d128d17a892529c0775a Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Thu, 1 Nov 2018 17:05:56 +0200 Subject: [PATCH] drm/i915: Clean up skl+ PLANE_POS vs. scaler handling MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit On skl+ the scaler (when enabled) will take care of the plane output position. Make the code less ugly by just setting crtc_x/y to 0 when the scaler is enabled.
