Subject: [PATCH 3/3] ARM: dts: at91: sama5d2 Xplained: use DMA for UART3
Date: Thu, 1 Dec 2016 11:49:49 +0100 [thread overview]
Message-ID: <20161201104949.23985-3-nicolas.ferre@atmel.com> (raw)
In-Reply-To: <20161201104949.23985-1-nicolas.ferre@atmel.com>
Use DMA for UART3 as we have enough channels and to show how to
specify DMA use with serial nodes.
