-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>;
- };
