From 46f788ba2e09c9f48d50f47e27c8e2cfc7e1c076 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Fri, 17 Mar 2017 23:17:55 +0200 Subject: [PATCH] drm/i915: Extract skl_plane_ctl() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Pull the code to calculate the SKL plane control register value into a separate function. Allows us to pre-compute it in the future.
