Linus Torvalds 4c8c225abf GPIO changes for Linux 3.9 
This branch contains the usual set of individual driver improvements and
 bug fixes, as well as updates to the core code. The more notable changes
 include:
 
 - Internally add new API for referencing GPIOs by gpio_desc instead of
   number. Eventually this will become a public API
 - ACPI GPIO binding support
