From 7108b436c2b53cf5d9c3a90139973bdee95898c8 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Wed, 1 Mar 2017 15:15:04 +0200 Subject: [PATCH] drm/i915/dsi: Execute MIPI_SEQ_TEAR_OFF from intel_dsi_post_disable For v3+ VBTs we should call MIPI_SEQ_TEAR_OFF before MIPI_SEQ_DISPLAY_OFF, v2 VBTs do not have MIPI_SEQ_TEAR_OFF so there this is a nop.
