1 | * Atmel Universal Synchronous Asynchronous Receiver/Transmitter (USART) | ||
2 | |||
3 | Required properties: | ||
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 | ||
9 | |||
10 | Optional properties: | ||
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 | ||
