- * Freescale MXS Application UART (AUART)
- Required properties:
- - compatible : Should be "fsl,<soc>-auart". The supported SoCs include
- imx23 and imx28.
- - reg : Address and length of the register set for the device
- - interrupts : Should contain the auart interrupt numbers
- Optional properties:
- - fsl,auart-dma-channel : The DMA channels, the first is for RX, the other
- is for TX. If you add this property, it also means that you
- will enable the DMA support for the auart.
- Note: due to the hardware bug in imx23(see errata : 2836),
- only the imx28 can enable the DMA support for the auart.
- Example:
- auart0: serial@8006a000 {
- compatible = "fsl,imx28-auart", "fsl,imx23-auart";
- reg = <0x8006a000 0x2000>;
- interrupts = <112 70 71>;
- fsl,auart-dma-channel = <8 9>;
- };
- Note: Each auart port should have an alias correctly numbered in "aliases"
- node.
- Example:
- aliases {
- serial0 = &auart0;
- serial1 = &auart1;
- serial2 = &auart2;
- serial3 = &auart3;
- serial4 = &auart4;
- };
