Subject: [PATCH v2 09/10] drm/i915/dsi: Call MIPI_SEQ_TEAR_ON and DISPLAY_ON for cmd-mode (untested)
Date: Tue, 28 Feb 2017 13:59:24 +0100 [thread overview]
Message-ID: <20170228125925.7020-9-hdegoede@redhat.com> (raw)
In-Reply-To: <20170228125925.7020-1-hdegoede@redhat.com>
According to the spec we should call MIPI_SEQ_TEAR_ON and DISPLAY_ON
on enable for cmd-mode, just like we already call their counterparts
on disable. Note: untested, my panel is a vid-mode panel.
