DEVICE TREE STRUCTURE(.dts file)USING PINMUX FOR BEAGLEBONE BLACK

THE PINMUX SETTING,BEAGLEBONE BLACK MODE AND PIN NO SELECTION CAN BE DONE  WHICH WILL BE LATER CONVERTED TO THE OBJECT FILE USING THIS SOURCE FILE.SO BASED ON THE REQUIREMENT IN UR PROJECT YOU USE THE PINS.AND RUN THE CODE IN TERMINAL WHICH SHOULD BE SAVED IN .dts EXTENTION,HERE IN DOWN WE USED IT FOR THE LED GLOWING A SIMPLE PROGRAM WE USED ONLY 5 GPIO PINS THOSE ARE GPIO15,GPIO45.GPIO60,GPIO44 AND GPIO23.
