   1 * Freescale i.MX Universal Asynchronous Receiver/Transmitter (UART)
   2
   3 Required properties:
   4 - compatible : Should be "fsl,<soc>-uart"
   5 - reg : Address and length of the register set for the device
   6 - interrupts : Should contain uart interrupt
   7
   8 Optional properties:
   9 - fsl,uart-has-rtscts : Indicate the uart has rts and cts
  10 - fsl,irda-mode : Indicate the uart supports irda mode
  11 - fsl,dte-mode : Indicate the uart works in DTE mode. The uart works
  12                   is DCE mode by default.
  13
  14 Note: Each uart controller should have an alias correctly numbered
  15 in "aliases" node.
  16
  17 Example:
  18
  19 aliases {
  20         serial0 = &uart1;
  21 };
  22
  23 uart1: serial@73fbc000 {
  24         compatible = "fsl,imx51-uart", "fsl,imx21-uart";
  25         reg = <0x73fbc000 0x4000>;
  26         interrupts = <31>;
  27         fsl,uart-has-rtscts;
  28         fsl,dte-mode;
  29 };
