ARM MPS2 UART
Required properties:
- compatible : Should be "arm,mps2-uart"
- reg : Address and length of the register set
- interrupts : Reference to the UART RX, TX and overrun interrupts
Required clocking property:
- clocks : The input clock of the UART
Examples:
uart0: serial@40004000 {
compatible = "arm,mps2-uart";
reg = <0x40004000 0x1000>;
interrupts = <0 1 12>;
clocks = <&sysclk>;
};
