Subject: [PATCH/RFC 04/15] drm: bridge: Add dual_link field to the drm_bridge_timings structure
Date: Thu, 7 Mar 2019 01:23:34 +0200 [thread overview]
Message-ID: <20190306232345.23052-5-laurent.pinchart+renesas@ideasonboard.com> (raw)
In-Reply-To: <20190306232345.23052-1-laurent.pinchart+renesas@ideasonboard.com>
Extend the drm_bridge_timings structure with a new dual_link field to
indicate that the bridge's input bus carries data on two separate
physical links. The first use case is LVDS dual-link mode where even-
and odd-numbered pixels are transferred on separate LVDS links.
