Subject: [PATCH RESEND FOR CI 08/10] drm/i915/dsi: Execute MIPI_SEQ_TEAR_OFF from intel_dsi_post_disable
Date: Wed, 1 Mar 2017 15:15:04 +0200 [thread overview]
Message-ID: <1488374106-4949-9-git-send-email-jani.nikula@intel.com> (raw)
In-Reply-To: <1488374106-4949-1-git-send-email-jani.nikula@intel.com>
From: Hans de Goede <hdegoede@redhat.com>
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.
