   1 * Qualcomm Atheros AR9330 High-Speed UART
   2
   3 Required properties:
   4
   5 - compatible: Must be "qca,ar9330-uart"
   6
   7 - reg: Specifies the physical base address of the controller and
   8   the length of the memory mapped region.
   9
  10 - interrupt-parent: The phandle for the interrupt controller that
  11   services interrupts for this device.
  12
  13 - interrupts: Specifies the interrupt source of the parent interrupt
  14   controller. The format of the interrupt specifier depends on the
  15   parent interrupt controller.
  16
  17 Additional requirements:
  18
  19   Each UART port must have an alias correctly numbered in "aliases"
  20   node.
  21
  22 Example:
  23
  24         aliases {
  25                 serial0 = &uart0;
  26         };
  27
  28         uart0: uart@18020000 {
  29                 compatible = "qca,ar9330-uart";
  30                 reg = <0x18020000 0x14>;
  31
  32                 interrupt-parent = <&intc>;
  33                 interrupts = <3>;
  34         };
