* 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";
|
||
|
|
};
