-* Qualcomm Atheros AR9330 High-Speed UART
-
-Required properties:
-
-- compatible: Must be "qca,ar9330-uart"
-
-- reg: Specifies the physical base address of the controller and
-  the length of the memory mapped region.
-
-- interrupts: Specifies the interrupt source of the parent interrupt
-  controller. The format of the interrupt specifier depends on the
-  parent interrupt controller.
-
-Additional requirements:
-
-  Each UART port must have an alias correctly numbered in "aliases"
-  node.
-
-Example:
-
-	aliases {
-		serial0 = &uart0;
-	};
-
-	uart0: uart@...20000 {
-		compatible = "qca,ar9330-uart";
-		reg = <0x18020000 0x14>;
-
-		interrupt-parent = <&intc>;
-		interrupts = <3>;
-	};
