Subject: [PATCH 6/6] dt-bindings: display: armada: Document bus-width property
Date: Sun, 20 Jan 2019 18:25:34 +0100 [thread overview]
Message-ID: <20190120172534.24617-7-lkundrak@v3.sk> (raw)
In-Reply-To: <20190120172534.24617-1-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.
