Reading LWN I came across this:

In short:
- there's new userspace API for working with GPIOs
- you can now enumerate them, they are character devices
- there's no way to use them yet but it is coming
- sysfs is deprecated

You may want to keep an eye out for this when working on tests for
GPIOs in various snappy devices. I will definitely take this into
account in snappy itself but it may be a while before that happens.

Best regards
