GPIO for Engineers and Makers - Linus Walleij

We will go over the changes to the GPIO subsystem in the recent years, including GPIO descriptor refactoring, new support for things like open drain, some words on device tree and ACPI hardware descriptions, and we will discuss the new userspace character device ABI for GPIO chips and how usecases such as those presented by the maker community or industrial control clients can benefit from it. We will also talk a bit about the future direction of the subsystem.
