I want to know on the below points : 1. How can I convert it into a GPIO driver and the standard ramework with which I can integrate it. 2.The architecture of the user space application to test this driver 3.The requirement for the Device Tree configuration for this. 4.The name of the LED class driver maintainer in the kernel linux, to whom I have to send the patch? 5.Any other mandatory requirement to which I have to adhere to for pushing the device driver to the main line. PS : I am using TI's beagleboard for developing the driver on the kernel 4.1x. Br, Rp
