* Mediatek Universal Asynchronous Receiver/Transmitter (UART)



Required properties:

- compatible should contain:

  * "mediatek,mt6589-uart" for MT6589 compatible UARTS

  * "mediatek,mt6582-uart" for MT6582 compatible UARTS

  * "mediatek,mt6577-uart" for all compatible UARTS (MT6589, MT6582, MT6577)



- reg: The base address of the UART register bank.



- interrupts: A single interrupt specifier.



- clocks: Clock driving the hardware.



Example:



	uart0: serial@11006000 {

		compatible = "mediatek,mt6589-uart", "mediatek,mt6577-uart";

		reg = <0x11006000 0x400>;

		interrupts = <GIC_SPI 51 IRQ_TYPE_LEVEL_LOW>;

		clocks = <&uart_clk>;

	};
