Kernel-3.10.0-957.el7_fsl-mxs-auart

• Freescale MXS Application UART (AUART)

Required properties:

• compatible : Should be “fsl,-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;
};
