From d426c517a7425dbd8e362051017b8acab20e8818 Mon Sep 17 00:00:00 2001 From: Paul Cercueil Date: Wed, 29 Aug 2018 23:33:00 +0200 Subject: MIPS: JZ4740: DTS: Add DMA nodes 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).
