Subject: [PATCH v6 09/20] drm/i915/icl: Get DSI transcoder for a given port
Date: Sun, 16 Sep 2018 16:23:32 +0530	[thread overview]
Message-ID: <1537095223-5184-10-git-send-email-madhav.chauhan@intel.com> (raw)
In-Reply-To: <1537095223-5184-1-git-send-email-madhav.chauhan@intel.com>

This patch adds a helper function to retrieve DSI
transcoder for a given DSI port using newly defined
enum names for DSI transcoders.
