UniPhier UART controller
Required properties:
- compatible: should be "socionext,uniphier-uart".
- reg: offset and length of the register set for the device.
- interrupts: a single interrupt specifier.
- clocks: phandle to the input clock.
Optional properties:
-auto-flow-control: enable automatic flow control support.
Example:
aliases {
serial0 = &serial0;
};
serial0: serial@54006800 {
compatible = "socionext,uniphier-uart";
reg = <0x54006800 0x40>;
interrupts = <0 33 4>;
clocks = <&uart_clk>;
};
