VIA/Wondermedia VT8500 UART Controller
-----------------------------------------------------
Required properties:
- compatible : "via,vt8500-uart"
- reg : Should contain 1 register ranges(address and length)
- interrupts : UART interrupt
- clocks : phandle to the uart source clock (usually a 24Mhz fixed clock)
Example:
uart@d8210000 {
compatible = "via,vt8500-uart";
reg = <0xd8210000 0x1040>;
interrupts = <47>;
clocks = <&ref24>;
};
