I doubt you will be able to convince the majority of people toggling GPIOs via a simple shell script to switch to write a complex C program. Not to mention cross compilation and the libraries dependencies here. Is there some good cli tools to access the new char device? If they are shipped with most distros, that would reduce the pain.

Instead of explicitly seeking to sanction the patentability of software, they are now seeking to create a central European patent court, which would establish and enforce patentability rules in their favor, without any possibility of correction by competing courts or democratically elected legislators." -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
