Subject: [PATCH v2 8/8] ARM: dts: r9a06g032: Describe the DMA router
Date: Tue, 22 Feb 2022 11:34:37 +0100	[thread overview]
Message-ID: <20220222103437.194779-9-miquel.raynal@bootlin.com> (raw)
In-Reply-To: <20220222103437.194779-1-miquel.raynal@bootlin.com>

There is a dmamux on this SoC which allows picking two different sources
for a single DMA request.
