From e99168f9f08644217d052808dd611dfe43e839cb Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Mon, 7 Jun 2021 19:24:57 +0200 Subject: [PATCH] drm/stm: Remove usage of drm_display_mode_to_videomode() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit There is not much value in the extra conversion step, the calculations required for the LTDC IP are different than what is used in the drm_display_mode_to_videomode(), so just do the right ones in the LTDC driver right away.
