Subject: [PATCH v4 18/18] MIPS: JZ4740: DTS: Add DMA nodes
Date: Tue, 7 Aug 2018 13:42:18 +0200 [thread overview]
Message-ID: <20180807114218.20091-19-paul@crapouillou.net> (raw)
In-Reply-To: <20180807114218.20091-1-paul@crapouillou.net>
Add the devicetree nodes for the DMA core of the JZ4740 SoC, disabled
by default, as currently there are no clients for the DMA driver
(until the MMC driver and/or others get a devicetree node).
Signed-off-by: Paul Cercueil <paul@crapouillou.net>
Tested-by: Mathieu Malaterre <malat@debian.org>
Acked-by: Paul Burton <paul.burton@mips.com>
