| * 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"; |
| }; |
