Subject: [PATCH v5 2/3] dt-bindings: display: sn65dsi83: Add output data-lanes property
Date: Fri, 17 Jul 2026 13:50:00 +0200 [thread overview]
Message-ID: <20260717115002.308035-3-wojciech.dubowik@mt.com> (raw)
In-Reply-To: <20260717115002.308035-1-wojciech.dubowik@mt.com>
From: Wojciech Dubowik <Wojciech.Dubowik@mt.com>
Add an optional output lvds data lanes property with two allowed values.
The array <1 2 3 4> for standard layout and <4 3 2 1> for reversed lvds
output lanes. The latter informs the driver that reverse lvds config
option has to be set in config register for the respective output channel.
