Understood,I thought there is some specific part number of the led like all other led drivers in the same folder. > You can find DT documentation for it in the following location: > > Documentation/devicetree/bindings/leds/leds-gpio.txt > I tried compiling the sample dts file(leds-ns2.dts) using the dtc compiler . dtc -I dts -O dtb -o leds-ns2.dtb leds-ns2.dts but I am getting this error : DTC: dts->dtb on file "leds-ns2.dts" Error: leds-ns2.dts:1.1-2 syntax error FATAL ERROR: Unable to parse input tree Once it starts compiling fine I will modify it according to my driver.Can I build the dtb and load it the way I load the kernel driver.Do I have to do it before or after the insmod ?
