Subject: [PATCH v7 9/9] ARM: dts: r9a06g032: Describe the DMA router
Date: Tue, 5 Apr 2022 10:19:11 +0200 [thread overview]
Message-ID: <20220405081911.1349563-10-miquel.raynal@bootlin.com> (raw)
In-Reply-To: <20220405081911.1349563-1-miquel.raynal@bootlin.com>
There is a dmamux on this SoC which allows picking two different sources
for a single DMA request.
