| * 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 |
| - dmas: DMA specifier, consisting of a phandle to DMA controller node |
| and AUART DMA channel ID. |
| Refer to dma.txt and fsl-mxs-dma.txt for details. |
| - dma-names: "rx" for RX channel, "tx" for TX channel. |
| |
| Example: |
| auart0: serial@8006a000 { |
| compatible = "fsl,imx28-auart", "fsl,imx23-auart"; |
| reg = <0x8006a000 0x2000>; |
| interrupts = <112>; |
| dmas = <&dma_apbx 8>, <&dma_apbx 9>; |
| dma-names = "rx", "tx"; |
| }; |
| |
| 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; |
| }; |
