+* 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.
+
+Additional requirements:
+
+ Each UART port must have an alias correctly numbered in "aliases"
+ node.
+
+Example:
+
+ aliases {
+ serial0 = &uart0;
+ };
+
+ uart0: uart@18020000 {
+ compatible = "qca,ar9330-uart";
+ reg = <0x18020000 0x14>;
+ };
