Pin Control and GPIO Update
By Linus Walleij
San Francisco, California

This session is intended to sum up the last say 24 months of changes with the creation of the pin control system and the changes related to GPIO as well as changes to the GPIO subsystem per se. We will know about the systems migrated to pin control, how device tree is used, pin to GPIO range mappings from either end, block GPIO control and how we try to move forward.
