4 - compatible: Should be one of the following:
5 	- "atmel,at91rm9200-usart"
6 	- "atmel,at91sam9260-usart"
7 	- "microchip,sam9x60-usart"
8 	- "atmel,at91rm9200-dbgu", "atmel,at91rm9200-usart"
9 	- "atmel,at91sam9260-dbgu", "atmel,at91sam9260-usart"
10 	- "microchip,sam9x60-dbgu", "microchip,sam9x60-usart"
11 - reg: Should contain registers location and length
12 - interrupts: Should contain interrupt
13 - clock-names: tuple listing input clock names.
15 - clocks: phandles to input clocks.
18 - #size-cells      : Must be <0>
19 - #address-cells   : Must be <1>
20 - cs-gpios: chipselects (internal cs not supported)
21 - atmel,usart-mode : Must be <AT91_USART_MODE_SPI> (found in dt-bindings/mfd/at91-usart.h)
24 - dma bindings for dma transfer:
25 	- dmas: DMA specifier, consisting of a phandle to DMA controller node,
27 		The order of DMA channels is fixed. The first DMA channel must be TX
28 		associated channel and the second one must be RX associated channel.
29 		Refer to dma.txt and atmel-dma.txt for details.
30 	- dma-names: "tx" for TX channel.
31 		     "rx" for RX channel.
32 		     The order of dma-names is also fixed. The first name must be "tx"
33 		     and the second one must be "rx" as in the examples below.
36 - atmel,use-dma-rx: use of PDC or DMA for receiving data
37 - atmel,use-dma-tx: use of PDC or DMA for transmitting data
38 - {rts,cts,dtr,dsr,rng,dcd}-gpios: specify a GPIO for RTS/CTS/DTR/DSR/RI/DCD line respectively.
41 - atmel,fifo-size: maximum number of data the RX and TX FIFOs can store for FIFO
43 - rs485-rts-delay, rs485-rx-during-tx, linux,rs485-enabled-at-boot-time: see rs485.txt
46 - at91rm9200:  legacy USART support
47 - at91sam9260: generic USART implementation for SAM9 SoCs
