Subject: [PATCH v2 10/10] [HACK] arm64: dts: renesas: ebisu: Enable LVDS dual-link operation
Date: Sun, 12 May 2019 00:07:02 +0300	[thread overview]
Message-ID: <20190511210702.18394-11-laurent.pinchart+renesas@ideasonboard.com> (raw)
In-Reply-To: <20190511210702.18394-1-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.
