Subject: [PATCH 2/2] dt-bindings: display: bridge: lt8912b: document 'lontium,pn-swap' property
Date: Tue, 2 Apr 2024 13:59:25 +0300 [thread overview]
Message-ID: <20240402105925.905144-2-alex@shruggie.ro> (raw)
In-Reply-To: <20240402105925.905144-1-alex@shruggie.ro>
On some HW designs, it's easier for the layout if the P/N pins are swapped.
The driver currently has a DT property to do that.
This change documents the 'lontium,pn-swap' property.
