From 395ab9da9322fb9dd208f9c4e3987d32bc911399 Mon Sep 17 00:00:00 2001 From: Matt DeVillier Date: Wed, 23 Dec 2020 17:30:27 -0600 Subject: [PATCH] soc/intel/common/gfx: rename and guard graphics_soc_init() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Rename to graphics_soc_panel_init, to more accurately convey operations performed by the function. Guard execution so we don't attempt to reconfigure the panel after FSP has already done so. This fixes FSP/GOP display init on APL/GLK, which was broken by attempting to configure the panel after FSP had already done so.
