Subject: [PATCH v1 1/3] dt-bindings: net: bcmgenet add property for max DMA burst size
Date: Fri, 11 Oct 2019 20:48:19 +0200 [thread overview]
Message-ID: <20191011184822.866-2-matthias.bgg@kernel.org> (raw)
In-Reply-To: <20191011184822.866-1-matthias.bgg@kernel.org>
From: Matthias Brugger <mbrugger@suse.com>
The maximal usable DMA burst size can vary in different SoCs.
Add a optional property to configure the DMA channels properly.
