* 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>;
};
