From mboxrd@z Thu Jan 1 00:00:00 1970 From: Paul Cercueil Subject: [PATCH v4 18/18] MIPS: JZ4740: DTS: Add DMA nodes Date: Tue, 7 Aug 2018 13:42:18 +0200 Message-ID: <20180807114218.20091-19-paul@crapouillou.net> References: <20180807114218.20091-1-paul@crapouillou.net> Return-path: In-Reply-To: <20180807114218.20091-1-paul@crapouillou.net> Sender: linux-kernel-owner@vger.kernel.org To: Vinod Koul , Rob Herring , Mark Rutland , Ralf Baechle , Paul Burton , James Hogan , Zubair Lutfullah Kakakhel Cc: Paul Cercueil , dmaengine@vger.kernel.org, devicetree@vger.kernel.org, linux-kernel@vger.kernel.org, linux-mips@linux-mips.org List-Id: devicetree@vger.kernel.org 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).
