Subject: [PATCH v2 14/14] ARM: dts: at91: at91sam9x5ek: use DMA for USART0
Date: Tue, 10 Oct 2017 13:09:49 +0300 [thread overview]
Message-ID: <1507630189-15504-15-git-send-email-claudiu.beznea@microchip.com> (raw)
In-Reply-To: <1507630189-15504-1-git-send-email-claudiu.beznea@microchip.com>
From: Nicolas Ferre <nicolas.ferre@microchip.com>
Use DMA for USART0 (which is used as ttyS1) as we have enough channels and to
show how to specify DMA use with serial nodes.
