1* Freescale i.MX UART controller 2 3Required 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 8Optional properties: 9- fsl,uart-has-rtscts: indicate that RTS/CTS signals are used 10 11Note: Each uart controller should have an alias correctly numbered 12in "aliases" node. 13 14Example: 15 16- From imx51.dtsi: 17aliases { 18 serial0 = &uart1; 19 serial1 = &uart2; 20 serial2 = &uart3; 21}; 22 23uart1: 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: 31uart1: serial@73fbc000 { 32 fsl,uart-has-rtscts; 33 status = "okay"; 34}; 35 36
