+* VIA VT8500 and WonderMedia WM8xxx UART Controller
+
+Required properties:
+- compatible: should be "via,vt8500-uart"
+
+- reg: base physical address of the controller and length of memory mapped
+ region.
+
+- interrupts: hardware interrupt number
+
+- clocks: shall be the input parent clock phandle for the clock. This should
+ be the 24Mhz reference clock.
+
+Aliases may be defined to ensure the correct ordering of the uarts.
+
+Example:
+ aliases {
+ serial0 = &uart0;
+ };
+
+ uart0: serial@d8200000 {
+ compatible = "via,vt8500-uart";
+ reg = <0xd8200000 0x1040>;
+ interrupts = <32>;
+ clocks = <&clkuart0>;
+ };
