Subject: [PATCH v5 18/18] MIPS: JZ4740: DTS: Add DMA nodes
Date: Wed, 29 Aug 2018 23:33:00 +0200 [thread overview]
Message-ID: <20180829213300.22829-19-paul@crapouillou.net> (raw)
In-Reply-To: <20180829213300.22829-1-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>

Notes:
v2: New patch in this series
v3: Modify node to comply with devicetree specification
v4: No change
v5: No change
