Sample led driver dts file

Hi, Can any one please send me the sample led driver dts file.I tried the sample from the /documentation/devicetree/bindings/leds/<dts file> but I am getting some parsing error from the dtc compiler. is "#" required while including the .dtsi file inside the dts while referring any include files. Also can we dynamically buil teh dts file and push/copy it to kernel? Reboot required? Thanks in advance , Rp
