* 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

Example:
auart0: serial@8006a000 {
	compatible = "fsl,imx28-auart", "fsl,imx23-auart";
	reg = <0x8006a000 0x2000>;
	interrupts = <112 70 71>;
};

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;
};
