API Support for Beaglebone Blue Week-9

[Kiran Kumar Lekkala]

Hi All!!

Finally, I am almost (there are still some fixes for the PRU) done with the coding part for my project. From this week onward, I'll be doing the testing and writing the documentation for all the APIs coded. This week I accomplished the following:

1. Finished coding the kernel driver for PRU-Servo to create sysfs entries. The firmware for PRU-Servo is also done.

2. Tested the button and LED API. Working perfectly!!
