Subject: [PATCH/RFC 15/15] [HACK] arm64: dts: renesas: ebisu: Enable LVDS dual-link operation
Date: Thu,  7 Mar 2019 01:23:45 +0200	[thread overview]
Message-ID: <20190306232345.23052-16-laurent.pinchart+renesas@ideasonboard.com> (raw)
In-Reply-To: <20190306232345.23052-1-laurent.pinchart+renesas@ideasonboard.com>

Enable and connect the second LVDS encoder to the second LVDS input of
the THC63LVD1024 for dual-link LVDS operation. This requires changing
the default settings of SW45 and SW47 to OFF and ON respectively.
