Subject: [BXT MIPI PATCH 1/2] drm/i915: Set the Z inversion overlap field for BXT
Date: Wed, 9 Dec 2015 17:29:57 +0530 [thread overview]
Message-ID: <1449662398-663-1-git-send-email-m.deepak@intel.com> (raw)
For broxton dual link Z-inversion overlap field is present
in MIPI_CTRL register unlike the other platforms, hence
setting the same in this patch.
