| 2 | |
| 3 | Required properties: |
| 4 | - compatible : should be "fsl,imx21-uart" |
| 5 | - reg : Address and length of the register set for the device |
| 6 | - interrupts : Should contain UART interrupt number |
| 7 | |
| 8 | Optional properties: |
| 9 | - fsl,uart-has-rtscts: indicate that RTS/CTS signals are used |
| 10 | |
| 11 | Note: Each uart controller should have an alias correctly numbered |
| 12 | in "aliases" node. |
| 13 | |
| 14 | Example: |
| 15 | |
| 16 | - From imx51.dtsi: |
| 17 | aliases { |
| 18 | serial0 = &uart1; |
| 19 | serial1 = &uart2; |
| 20 | serial2 = &uart3; |
| 21 | }; |
| 22 | |
| 23 | uart1: serial@73fbc000 { |
| 24 | compatible = "fsl,imx51-uart", "fsl,imx21-uart"; |
| 25 | reg = <0x73fbc000 0x4000>; |
| 26 | interrupts = <31>; |
| 27 | status = "disabled"; |
| 28 | } |
| 29 | |
| 30 | - From imx51-babbage.dts: |
| 31 | uart1: serial@73fbc000 { |
| 32 | fsl,uart-has-rtscts; |
| 33 | status = "okay"; |
| 34 | }; |
