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

<chip> compatible description:
|
||
|
|
- at91rm9200: legacy USART support
|
||
|
|
- at91sam9260: generic USART implementation for SAM9 SoCs
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
usart0: serial@fff8c000 {
|
||
|
|
compatible = "atmel,at91sam9260-usart";
|
||
|
|
reg = <0xfff8c000 0x4000>;
|
||
|
|
interrupts = <7>;
|
||
|
|
atmel,use-dma-rx;
|
||
|
|
atmel,use-dma-tx;
|
||
|
|
};
