On our AT91SAM9G25-based GARDENA smart Gateway we have been experiencing
various problems which we were able to trace back to unreliable UART
communication. Enabling DMA for the serial ports resolved these issues.

  ARM: dts: at91: at91sam9x5ek: Use DMA for DBGU serial port
  ARM: dts: at91: gardena-smart-gateway: Use DMA for USART3
