Subject: [Intel-gfx] [V14 1/5] drm/i915/dsi: Add details about TE in get_config
Date: Thu, 24 Sep 2020 18:12:05 +0530	[thread overview]
Message-ID: <20200924124209.17916-2-vandita.kulkarni@intel.com> (raw)
In-Reply-To: <20200924124209.17916-1-vandita.kulkarni@intel.com>

We need details about enabling TE on which port
before we enable TE through vblank enable path.
This is based on the configuration that we receive
from the VBT wrt ports, dual_link.
