Subject: [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)

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).
