1 * Freescale i.MX Universal Asynchronous Receiver/Transmitter (UART)
4 - compatible : Should be "fsl,<soc>-uart"
5 - reg : Address and length of the register set for the device
6 - interrupts : Should contain uart interrupt
9 - fsl,dte-mode : Indicate the uart works in DTE mode. The uart works
10 in DCE mode by default.
11 - rs485-rts-delay, rs485-rts-active-low, rs485-rx-during-tx,
12 linux,rs485-enabled-at-boot-time: see rs485.txt. Note that for RS485
13 you must enable either the "uart-has-rtscts" or the "rts-gpios"
14 properties. In case you use "uart-has-rtscts" the signal that controls
15 the transceiver is actually CTS_B, not RTS_B. CTS_B is always output,
16 and RTS_B is input, regardless of dte-mode.
18 Please check Documentation/devicetree/bindings/serial/serial.txt
19 for the complete list of generic properties.
21 Note: Each uart controller should have an alias correctly numbered
30 uart1: serial@73fbc000 {
31 compatible = "fsl,imx51-uart", "fsl,imx21-uart";
32 reg = <0x73fbc000 0x4000>;
