Where can I find the example for the  dynamic Loading of the device
tree and its corresponding device driver.
How can I build the dts with or without the kernel source.

I am getting this error whenever I am trying to build the below sample
dts file using the dtc compiler.

dtc -O dtb -o leds-ns2.dtb leds-ns2.dts

Error: leds-ns2.dts:1.1-2 syntax error
FATAL ERROR: Unable to parse input tree

Below is the content  of the leds-ns2.dts

#include <dt-bindings/leds/leds-ns2.h>

 ns2-leds {
          compatible = "lacie,ns2-leds";

          blue-sata {
                  label = "ns2:blue:sata";
                  slow-gpio = <&gpio0 29 0>;
                  cmd-gpio = <&gpio0 30 0>;
                  modes-map = <NS_V2_LED_OFF  0 1
                               NS_V2_LED_ON   1 0
                               NS_V2_LED_ON   0 0
                               NS_V2_LED_SATA 1 1>;
