* Freescale i.MX UART controller
Required properties:
- compatible : should be "fsl,imx21-uart"
- reg : Address and length of the register set for the device
- interrupts : Should contain UART interrupt number
Optional properties:
- fsl,uart-has-rtscts: indicate that RTS/CTS signals are used
Note: Each uart controller should have an alias correctly numbered
in "aliases" node.
Example:
- From imx51.dtsi:
aliases {
serial0 = &uart1;
serial1 = &uart2;
serial2 = &uart3;
};
uart1: serial@73fbc000 {
compatible = "fsl,imx51-uart", "fsl,imx21-uart";
reg = <0x73fbc000 0x4000>;
interrupts = <31>;
status = "disabled";
}
- From imx51-babbage.dts:
uart1: serial@73fbc000 {
fsl,uart-has-rtscts;
status = "okay";
};
