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 - fsl,inverted-tx , fsl,inverted-rx : Indicate that the hardware attached
12 to the peripheral inverts the signal transmitted or received,
13 respectively, and that the peripheral should invert its output/input
14 using the INVT/INVR registers.
15 - rs485-rts-delay, rs485-rts-active-low, rs485-rx-during-tx,
16 linux,rs485-enabled-at-boot-time: see rs485.txt. Note that for RS485
17 you must enable either the "uart-has-rtscts" or the "rts-gpios"
18 properties. In case you use "uart-has-rtscts" the signal that controls
19 the transceiver is actually CTS_B, not RTS_B. CTS_B is always output,
20 and RTS_B is input, regardless of dte-mode.
22 Please check Documentation/devicetree/bindings/serial/serial.yaml
23 for the complete list of generic properties.
25 Note: Each uart controller should have an alias correctly numbered
34 uart1: serial@73fbc000 {
35 compatible = "fsl,imx51-uart", "fsl,imx21-uart";
36 reg = <0x73fbc000 0x4000>;
