Subject: [Intel-gfx] [V4 5/8] drm/i915/dsi: Use private flags to indicate TE in cmd mode
Date: Fri, 27 Dec 2019 15:26:26 +0530 [thread overview]
Message-ID: <20191227095629.1796-6-vandita.kulkarni@intel.com> (raw)
In-Reply-To: <20191227095629.1796-1-vandita.kulkarni@intel.com>
On dsi cmd mode we do not receive vblanks instead
we would get TE and these flags indicate TE is expected on
which port.
