Subject: ARM: dts: at91: sama5d2: add dma properties to UART nodes
From: Nicolas Ferre <nicolas.ferre@atmel.com>
commit b1708b72a0959a032cd2eebb77fa9086ea3e0c84 upstream.
The dmas/dma-names properties are added to the UART nodes. Note that additional
properties are needed to enable them at the board level: check bindings for
details.
