Some Chromebooks have gpio attached to signals used to cause the firmware to enter alternative modes of operation and/or control other device characteristics (such as write protection on flash devices). This patch adds a driver that exposes a read-only interface to allow these signals to be read from user space.
In addition this patch series provides the required bindings for this to the peach-pi Chromebook.
