Subject: [PATCH v4 5/5] dt-bindings: display: armada: Document bus-width property
Date: Wed, 28 Aug 2019 09:59:38 +0200 [thread overview]
Message-ID: <20190828075938.318028-6-lkundrak@v3.sk> (raw)
In-Reply-To: <20190828075938.318028-1-lkundrak@v3.sk>
This makes it possible to choose a different pixel format for the
endpoint. Modelled after what other LCD controllers use, including
marvell,pxa2xx-lcdc and atmel,hlcdc-display-controller and perhaps more.
