1 * Atmel Universal Synchronous Asynchronous Receiver/Transmitter (USART)
4 - compatible: Should be "atmel,<chip>-usart"
5 The compatible <chip> indicated will be the first SoC to support an
6 additional mode or an USART new feature.
7 - reg: Should contain registers location and length
8 - interrupts: Should contain interrupt
11 - atmel,use-dma-rx: use of PDC or DMA for receiving data
12 - atmel,use-dma-tx: use of PDC or DMA for transmitting data
