Required properties:
|
|
- compatible : Should be "fsl,<soc>-uart"
|
|
- reg : Address and length of the register set for the device
|
|
- interrupts : Should contain uart interrupt
|
|
|
|
Optional properties:
|
|
- fsl,uart-has-rtscts : Indicate the uart has rts and cts
|
|
- fsl,irda-mode : Indicate the uart supports irda mode
|
|
- fsl,dte-mode : Indicate the uart works in DTE mode. The uart works
|
|
is DCE mode by default.

Example:
|
|
|
|
serial@73fbc000 {
|
|
compatible = "fsl,imx51-uart", "fsl,imx21-uart";
|
|
reg = <0x73fbc000 0x4000>;
|
|
interrupts = <31>;
|
|
fsl,uart-has-rtscts;
|
|
fsl,dte-mode;
|
