Subject: [PATCH v3 7/7] ARM: sun6i: dt: Add A31 DMA controller to DTSI
Date: Tue,  4 Mar 2014 17:18:04 +0100	[thread overview]
Message-ID: <1393949884-892-8-git-send-email-maxime.ripard@free-electrons.com> (raw)
In-Reply-To: <1393949884-892-1-git-send-email-maxime.ripard@free-electrons.com>

Now that we have a DMA driver, we can add the DMA bindings in the DTSI for the
controller and the devices supported that can use DMA.
